Well, I can't stop you from spriting more of them if you wanted to, you can do that like any kind of fanart of course, but If I do get around spriting them, I will want to do all of them myself regardless.
... and I thought questions like these you didn't like? I got an idea. Why don't you draw up a new pose for all of them, resize them and turn them into sprite art? That way they'd looked "scratch sprited" as well, and not something like my sprite, which has the exact same pose as the real one.
Ive been thinking about that recently actually. Since my art isn't proper sugimori art, I might as well do sprites instead of my previous plan to make better art for all of them once I hit 200.. but either way, its a time-consuming task of course.
Hey you are an inspiration for me, with your Fakemon. (This is an annoying question) But why couldn't you sprite them up? I tried Cycadino and it came out nice. IMO your spriting skills are good judging by that world map.
