Thanks for the tips, mate!
I may not be able to work on this for a month now considering I've my hands tied with "Hunter" Project, a one-minute film. Though, once I'm done I'll return to finish this: it's actually a part of
yet another AMV project of mine, relevant to Crono's final duel with Dalton. For some reason I prefer artistic-unrealistic shading style, similar to Blackwater Gospel, than any realistic rendering, and that's exactly what I'm focusing on.
And indeed, both Inkscape and Illustrator are rad!
Of course, I'm more of a supporter of OpenSource though. And holy shit, I dig that lighting/shading of your wallie!
Even without that Photoshopping it's... it's...
You seriously need to make a tutorial for it.
