What a gorgeous cervine! I love how delicate she looks. : ) Did you try using references first, before drawing from memory? I found a photo that is pretty close to your pose here: http://www.wjsteele.com/blogimages/deer.jpg

Deer generally have bigger tummies than what I am seeing here. Their backs also do not slope quite that way, as seen in the photo.

Mostly though, I was excited at finding a photo so close to the picture here. I hope it is helpful!

Also, I think the hair looks really cute on the character. :3 And I especially love how you did her little nose.

Heh, this one's all from memory, I definitely could benefit from using refs. Thank you very much for the critique, very constructive, I'm trying to make my deer look less equine. Poor girl here has a horse back. And a dog stomach. I'll be working on that.
