Looking good, I really like him. You should try to give his face a bit of a snarl though. It's kinda a tiger trademark. You should try to match his colours with actual tiger markings, he looks like he's suppost to be a tiger warrior, and not actual look like a tiger warrior.
Hey I'm currently creating a African Warrior for part of my university coursework. I Haven't used Zbrush very much, only properly during this semester but anyways. I would appreciate any comments on the model and be harsh! I only want to get better and leading me on won't do any good =D.
