This is a photo of a doodle I made on request from my friend of BlackJack from Percy Jackson. Character obviously not mine, but drawing is. Sorry for the bad quality, my iPad won't hold still... :P

This is the fifth style of art, and it is more realistic. This drawing took me five days of in-class doodling to complete, so obviously it will take me a LOT longer to make the covers. Also, this drawing is very smudged after being stuffed into my backpack several times...  This style is better for chapter covers, book covers will take forever... I can also not guarantee that it will look good in color, I'm best at black and white. And they have to be on paper, sorry.
