Dart Frog - player character for FPS

This is a player character model I made for an upcoming indie game project (a multiplayer FPS), being developed in Unity.
The character was designed (and the concept art drawn) by me, based on a brief description by the client. I'm pretty happy with the results!

Concept art by me!
The final model ended up having a few changes: a reduction of fingers and toes for easier animation, reduction of relative size of the weapon, and a change of texture pattern.
