Thanks for the suggestions. It took me a while to wrap my head around it but in the end I was able to build the character from quads, with only 2 or 3 exceptions. I looked at the alien tutorial but the character seemed way to advance for me at this point. I'll do one or two more low-poly characters before moving on the aline.. Anyways.. I got my character finished. I'm pretty happy with the result, ended up under 2000 tris. I don't plan to smooth him (subdiv proxy + crease tool), but I did just to test the geometry and everything works fine, everything but the mouth. Every other edge got rounded but the mouth keeps its original edges. Any idea why? Anything ticked under Preserve? Might be either one of those 2, if not the problem's with the mesh.
