First one ever :o It was really fun!
The only thing is, with wolves their muzzles/snouts are a bit longer, but I prefer to draw cats with very short snouts, and wolves/canines with a more protruding one.
Proportions too,
And finally (I can't do wolf tails very well) But wolf tails aren't very long, and they don't go "Up" much.
But I can't redline well yet, so my proportions were off since I forgot the opacity at first.
