I have been thinking...
I am willing to participate and help you to bring the comic forward. I can create any custom sprite you need. Time is my friend.
I may be a NES graphic expert, but I know a good deal about how to shade sprites.
Afterall I started graphic designing with Zero Series sprites.
I can even improve, preexisting sprites.
Allow me you to show you my refined SNES X sprites from 17 months ago. http://i.imgur.com/9jRzDle.png (I admit X is sparkling like a polished car)
