Here you go!
I decided to go over the entire thing including the head. I decided to use a more realistic style, just so you could get a sense of anatomy. It was a little difficult because of canvas size.
TIPS:
Make sure shoulder and knee line up.
Make the muzzle a little longer.
Try to keep the body natural-looking, not too skinny, not too chunky.
Study up on bone structures of canines.
I'm am not an expert on wings haha.. but anatomy I'm great at because I've been studying it for years. If you have any questions feel free to ask!
