These are only some that I've done. Most take less than a week, but I've been told I work fast in art class, so yeah. Feel free to use the reference images. If you want my drawings for anything, or want more of mine, let me know/credit me, please. 

This was one of my first ones in Art I, as well as the two below. That's why it looks kinda cruddy. It was before I knew about blending stumps and blending shadows too.

This my pony Ellie, she passed away two years ago, and when I had a free assignment, I tried different media with this pic (the first/colored pencil is more proportional, but the second is shaded better...):

This one isn't my horse... (also from Art I):

This is me, we were trying a viewpoint lesson in Art II. You can play around with proportionality as well as color and lines and shading if you don't want to be realistic.

This was my second semester final for Art II (yes, the eye is supposed to be blue):

This one was for my first semester final of Art I:

I did this tiger along with the lion above for first semester final (together took about a week and a half I think); both are subtractive drawings, just like the wolf (sorry about the glare):

This one was just to mess with colored pencils and color schemes. I think I personally had too much color here, but the skull was meant to be warm while the flowers were cool colors... maybe I shouldn't have outlined? (I had multiple reference images for this one, so I didn't want to post them, that and I lost them).
