I like the design:
1. It is strong and simple.
2. It is easy to read from a distance.
3. It has the right amount of detail that isn't over powering and just make the character look even cooler up close.
4. The character looks great as it is, so if you add the right color scheme to it. You can have him ready to go for his big roll in a comic or a short animation.
5. And lastly the character looks like a great bass for a who series of new characters / acquaintance of the character.
For example just add a bow, slim up the arms, and turn the shoulders and chest into triangles and you got your self a girlfriend and/or partner for your character.
