Hmm... You've definitely improved since your last one, but in the original, you did some things that are essential to realism. For the fur, try using different shades, and use the Pencil tool on size one to make lines of different shades of the same colour. Then use the smudge tool to make it look more fur-like. Also, just practice your wolf eyes some more, because yours are a bit too big, and a bit too round. That's okay though; just keep practicing and you'll get better!

One last thing: you can also use the smudge tool (Size 3 works best) like you did in the first picture. Try making your wolf look a little fluffier, so he/she doesn't look bald.
