Foamwork Crits

Hello again! Ive been so indecive lately! I need some help with this foamwork Ive been working on for a red panda.

Everything is pinned right now, so it looks a bit awkward! ^^;

Of course, the foamwork is not finished, but to me, the smile looks awkward. Any tips to make this work would be highly appreciated! Thanks in advance!
