Hi there, I'm very new to Illustrator and it's been some days (if not weeks) that I'm trying to find a solution for this problem.

I basically had an image in the background and used the pen tool on top to reproduce the different lines. So at the moment it's all paths. But as you can see, the outer line is all together.

What I want to do is to join the top lip path into one shape, lower lip other shape, tongue another, and so on. The idea is to paint each of those shapes in different colours but I can't find a way to join them or even separate the outer line (I tried scissor, eraser, cut in the anchor, but no luck).

Any help would be much appreciated (or suggestion on the right way of doing something like this).
