Whats wrong with my smile?

I am a pretty average looking person and im okay with being average but ive been really insecure about my smile since middle school. I hate how goofy my teeth look, how my lower face puffs out when i smile, and worst of all i hate the weird lines that appear in my lower cheek. If anyone can figure out what the problem is and if there is anyway to fix it id be forever grateful.

Ps. Im female, early 20s, my cheekbones and jaw are quite wide with my jaw being slightly wider than my cheekbones, my cheekbones dont have much anterior projection. My chin is slightly recesses but i have no bite issues.
