Its a cute stamp, but not to be pedantic or anything, but to me the front legs look a little off when they reach forward, and it makes the wolf look like its skipping (if quadrupeds could skip) rather than running. If you look at other examples of a wolf running, usually they stretch out a bit more returning the front paws back to the earth.
The only I have a teeny tiny problem with is that it doesn't look like the wolf is actually running....the ground doesn't move.... I still love it though! Awesome stamp! I loved the comic by the way (needs an UPDATE!)
