Alright, so I've been thinking about this for a bit, but I never got to posting it.
What if, we could have up to two markings on each body part? Like, two body markings, two head markings, and two tail markings. But it'd be optional, so you could have, let's say, two tail markings, and one body marking, and no head markings. Or two markings on body, head, and tail. Or one marking on body, head, and tail. Or no markings. (Or whatever way you want.) So what I was thinking is like, you're onto the choosing your markings for your character part, and you select a marking, and hold, I don't know...control? Yeah, I'll use that as an example. So, you hold down control, and can select another marking.
However, I don't think you should be able to have any more than two markings, or that can be a little pointless...
Anyway, tell me, what do you all think?
