Panicing about my ap drawing portfolio !

Can someone who previously took ap art studio: drawing help me evaluate my crappy art portfolio? My main problem is that i don’t draw that much still life (i draw portraits all the time) my concetration is about whether are skeletons symmetrical or not (still got 2 more drawings in the class) and working on 3 more right now. I’m not majoring in art, i just want a 3or 4 (i know my expectations are sky high lol) i used colored pencils, paint tool sai and pen as my tools
Here’s a few works i’ve done:
