You can use your imagination; what you just described sounds fantastic
So yeah, that's
why I wanted to see if anyone wanted to do concept art, just to get ideas of what to make them look like in the first place. The sprites on the last page are from Megaman Zero, and they're simply being used as placeholder sprites in the demo engine I'm making up (because I can't sprite to save myself).
By the way, the development forum is nearly up and running, so I might be inviting some people to it soon
