I like 'em. Maybe you'd have fun doing a non-sprite fan comic? Something to think about... I might except that I can't draw Mario characters that well... they end up very stylized and not much like the originals... hey, that might not be bad... I might want to do that...
But back on topic, they are amazing sketches. The really look like the artwork from PM2. Do you have any more sketches, like of your own characters, that you could show us :D
Hmmm... I don't think I'd be very good with off-game pictures. Both Bobbery and the Yoshi Kid's poses were sketched from pictures online. I'm not very original, but I can sketch something that I see (depending on how dificult it is. xD).
I'd love to get more pictures up, but, my scanner's broken and I'm back to school now. So, I don't have the time, or the machinery, to do so. ;( Sorry guys.
