Fantastic Re-imaging
The pose, the colours, the shading. It's all so dynamic. I mean seriously, this jumps out at me. The thing that makes me enjoy this is that despite this being a reimaging into a more serious and dynamic take on Zim, it still feels recognizable.
The rather interesting thing is, I imagine this is how Zim views himself. :)
Keep up the stellar work!
