Well, I'm doing art GCSE at the moment, and looking around at other people's pieces has inspired me to do a few Bionicles of my own.
My first piece is Matoran Nuparu before the rebuild. Please let me know if you like it, I'm pleased with it, but if I get the silent treatment I might freak out a little. I might make a piraka next, I reckon it would look good in this style. Most my digital art is in this freaky, blotty style. It starts off in pencil, I get a sketch done over about an hour, than I import it into photoshop, texture it, colour it, sort out the lighting, and figure some sort of background.
My art style when I photoshop it like this tends to be reminiscent of post-apocalyptic I think, so a Piraka could look kinda cool.
