I have a cheap sprite testing sheet, and I could not make a full sheet because I was having difficulties when I rotated it 45 or 22.5 degrees. But I'll show you the sheet, if you like my progress, I could shade it or something, but I'm sure someone else can find a way to rotate it, right?
unshaded, no transparency yet, did a few things, couldn't get it to turn out right, but tell me what you think.(i only drew them from scratch, not really hard at all)
