Head critique/redlines

Hello everyone :)

So I'm working on a tiger fursuit. This is my first feline fursuit (well, besides TLK one that I made in the Disney style). I'm struggling to make sure I am doing okay with the anatomy. I mean, I know this isn't a realistic suit. It is a more toony one, but I still like to have close to the actual anatomy of the species I'm making.

There are things I know are wrong/need fixed for sure. The very odd smile line on the sides is just horrid. That won't be there in the finished work. I also have that chunk of foam on the bottom of the jaw there and it really isn't for anything yet. I am going to use it to bulk out the lower jaw some later on.






So anyway, any advice is awesome! Thanks
