This is my first critique so I hope I do a good job and I hope I don't look stupid.
This is truly amazing, I am blown away from the colors and how you kept to the real doll (The pink on the body and arms) I also, like how it looks like a sketch with it still being digitally colored. The only thing I'm on fence about is that the shoes almost blend into the skin. But, all together this is a beautiful and cute piece of art and you should definitely be proud of this!
I love this drawing, for a start. I guarantee that a lot of people will love it - I'd love to see some more of these drawings!
I like how you kept the pink in the design, and also how the wings are pointed to one side rather than spread out on each side. A very creative technique.
There are only two things I'm not blob on about. First, the shoes do blend in a lot, so I think that some outlining would be good. Secondly, the hair is a bit...different, dare I say? I think there isn't enough black in the hair.
Overall, absolutely love this piece of art. Keep it up!
