Both are rather dark in color so it's a little hard for me to
pick out all the details.
Over all it's a pretty good work, but you asked for a critique so here
goes on the first one.
It appears the muzzle has a bit of a twist as the nose, teeth are at
a different angle than the eyes. Nose more clockwise than the eyes.
The canines are angled even more clockwise.
Also the characters left ear looks to be a bit lower than it's right. Probably
would look better if the right ear didn't show all that much.
You proabably should practice a little more on canine teeth too.
One thing to remember in art is always try to make the little details
look good. They can make or break the whole picture.
The only tip I have on the second drawing is to watch your perspectives, and
details. Other wise it's a good background drawing.
One other thing that is good to do. Check the sketch in reverse before
you start coloring. I always try to do that when I draw.
Keep up the good work.
