REVIEW :

1. Cover, Title, Summary (8/10)
Cover shows the portrait of the lead cast. It relates the characters, as well as the theme & plot of the story. But, it doesn't show relevance towards the title, which it should (Read Advice section)
The title basically depicts any one of the many elements related to the book, eg.- the theme/ characters' motive/ gist of the plot / genre etc. Your book's title relates well to the storyline and theme of story.
Summary needs improvement, as many grammatical, spelling mistakes are present.

2. Images/photos etc., audio, video, GIFs- Graphics (7/10)
Images- cover photo, characters' photos & some magical land pictures. None other graphics used. But, I believe that the images used, suit the character description as well as the storyline, and other graphics aren't needed.
Though, I don't judge any story based on the presence of graphics, but it sure does entice a reader to further delve in the book. I understand that it takes times for incorporating such features, and I wish the author good luck, for that.

3. Grammar, Spelling, vocabulary (5/10)
Spelling mistakes- present and I am afraid there are many, eg. 'themself' in place of 'themselves', 'energi' in place of 'energy' etc.
Grammar: Punctuation - comma, single & double quotation marks mistakes, period placement, verbs usage and verb tenses (eg.- 'was' in place of 'were', 'build' in place of 'built' etc.) at many places. The placement of defining & non defining clauses, with determiners also need editing in chapters.
Word mistakes - more than few, but present, eg. 'too' is used in place of 'to', 'know' in place of 'now' etc.
Word repetitions are also present and may be reduced, at some places.
Vocabulary is kept simple, but appropriate and good for acquainting the reader well with the story.

4. Literary elements: plot, setting, characterization, conflicts, POVs, mood, tone (6/10)
The plot is magical, it's environment is chosen appropriately and attracts readers who love fantasy. But, the background information, in prologue, should be elaborated, to build interest.
The time when it happens (history eg. 1860, or present or future time) and the place must be clearly mentioned.
Settings (meaning living environment, clothing, conversation styles, food habits, Transportation, etc., as per the time cited in story) need elucidation too.
Characters are developed gradually with their magical abilities & behavioral patterns, introduced in the first few chapters. Though their thoughts, feelings, concerns etc., may be included too.
Conflicts are properly woven with the story.
The book is written in third person  POV, and author attempted to write communicatively. The starting chapters are written describing each character per chapter, which highlight their powers very interestingly, giving slight insight into their works/family/people interactions. Moods (these are the emotions aroused in the reader by the write up) induced- amusing, enthralling. Tones(meaning author's attitude) are preternatural & whimsical. In short, POV, moods, tones are effectively presented.

5. Diction, writing style, pacing (4/10)
Diction is good, with a nice & fitting choice of words, but at some places the choice of adjectives, nouns, adverbs need replacement for providing the reader a good imagination (called imagery).
Writing style is narrative and pacing seems fast, especially in the Prologue section, with events & conflicts described hurriedly.

6. Allusion, epigraphs, euphemism, foreshadowing, metaphors/simile, imagery (5/10)
Foreshadowing is properly used throughout book chapters. The author divulges little information, with each chapter which, while satiating readers' curiosity, keeps him bound for continuing to the next chapter.
Author tried to use imagery, but it still need refinement, in the chapters.
Other devices not used, which may be due to the story requirements.

7. Structuring (8/10)
Starting & ending clearly presented in text. Paragraphs, dialogues are properly structured. Chapters names are precisely chosen according to the person's POV. It would be professional & convenient for a reader, if chapters are numbered too. Prologue proves to be the book's strength, as the plot background gives much needed spice.

8. Cliffhangers, twists/turns/incident presentation (9/10)
Cliffhangers are maintained throughout Chapters.
The storyline is intriguing & engaging.
Some scenes need elaboration at a few places.
Twists and turns are abundant which maintain reader's curiosity & keeps him bound.

9. Originality, creativity (3/10)
Not much originality or creativity.

Rating/Marks :
8+7+5+6+4+5+8+9+3= 55/90

Reviewer's note:
The story is interestingly put, and readers who like fantasy will find it amusing.

ADVICE (to author):

1)To take the suggestion or not, is at author's discretion, but my opinion is, according to the title, the cover image should include the picture of magical tree embedded in between the cast.
The author may also include some more related images of the magical land and magical creatures/beings, with that aura surrounding them.

2) Prologue may include the lead characters, highlighted in some situation, which includes their role in the story background. This will acquaint readers of the cast and also make it interesting to read further.
