Original sketch was interesting enough, but I am not sure if i did it any good by complicating it and tweaking proportions and the rest.
I slapped in an original bluepencil cleanup. If someone wants to colour it, be my guest.
For the final one, I slapped some gryscale makers, and scanned it in again, placed it on top of the linework, tweaked a bit, and voila!...
Or whatever. I think it's stiff and needs to be better.
