You should be proud. This is an interesting concept.
The Anatomy is off, but in time this will improve.
I like that you didn't go for an outline look for your piece, it gives it a semi-realistic feel... if you know what I mean.
I wish you the best in the C.O.T.M. :)

It's amazing that you got this off of your phone. The textures must've taken you forever to do.
It's a really well-done piece.
This is my first time entering too, and I wish you the best of luck!

It looks to be traditionally done, which is awesome. I, myself, like Traditional a bit more than Digital.
Very cute drawing, I like this a lot.
The reason I didn't go for the full 5-star rating is because the picture quality of your piece seemed to dull it, near the middle mostly, where there might have been a flash of some kind.
Don't get me wrong here: It is a really good piece, you did an amazing job with it. Keep up the good work. XD
