Wolf, crow and squirrel sprite art

These are sprite arts I made for a project. There are four sprites in total: a wolf, crow, one standing squirrel and one climbing squirrel. All have attack and hurt animations. The wolf has a running animation, the crow only a flying one. The climbing squirrel attack animation is paired with the acorn sprite as that is the projectile it is attacking with. 

The wolf and squirrel were meant to be used as the player characters. The squirrels are enemies. I also have sprite art of second level squirrel enemies, as well as a boss. In case of interest, let me know and I'll send them.
