Wolf Pack

Now I know this isn't perfect, I've already had a whinge
I'm not happy with the middle one as the head is too big, and have drawn the paws and forelegs too small in comparisson to this, possibly under influence from the wolves next to the centre one. I'm still getting used to drawing paws (I used to draw horses non stop a few years ago and took me a while to adjust to paws.

Any other points or things you want to point out are welcome.
