Pretty much all of the critique for this piece is in regards to her anatomy. That you used food coloring for this is very interesting! The purple is a great shade, and it's refreshing that you didn't color in or shade the rest of her body, because it allows the purple to rule. I think this piece is a great start! Her anatomy is just off in a few places. I think it would be worth your while to use some reference pictures until you get a handle on anatomy (artists never stop using reference pictures, no matter how good they get, so you should never be afraid to use them). Here are a few quick pointers: ~Her jawline is very long, making her face look more masculine than what you probably want. ~Her shoulders are much wider than her hips. A genereal rule of thumb with drawing women is that their shoulders and their hips should be about the same width. ~Her breasts are very high up on her torso. Also, her groin is undefined. Next time, you should take care to leave a small triangle to remind you where her groin is, that way it doesn't disappear into her clothing. Her shorts should fold around her groin. I think this is a beautiful start, and once you get a handle on your anatomy, I think you will go far as an artist! Keep up the good work!
