Hi! I've a detailed anime style I think might be to your liking. I'm big a fan of armour and mechanical parts. I've more in my gallery in my sketch dumps.
Depending on how much of the character in the shot or if you want it as a pencil sketch, ink, cell shaded anime screen shot style (e.g. [link]) or full coloured character (e.g. [link]) the prices can vary. A detailed coloured full body shot of this guy with this will likely cost $50 and I'll throw in the PSD file~
