This is actually part of an undergoing collab with http://blueike.deviantart.com/, in which he'd be doing the colorization of a sketch featuring Vector and Oinkers, but I decided to color just Vector as an outlet to do some experimentation with my shading process. Of course, there may be some kinks here and there, but the ultimate result is that the shading will make use of an extra level of shading, which would allow further hue-shifting and color vibrancy. What do you guys think of it?
