A couple of poses

Hello! I’m newer to the site and this is my first time asking for critique!

How am I generally doing? What would you suggest focusing on? Thank you for any and all help!  Have the most amazing day!  Critique

Nicely done. Your linework describes the shapes beautifully (particularly the 2nd and 3rd images). You did a great job of capturing the twisting forms in the 3rd - the feet are great (feet can be hard). 

I do think the heads  in both of those figures seem the wrong proportion to the bodies - they appear to be on the small side. There’s something that seems off about the back knee in the 3rd - looks like a side view of the knee, but the foot is facing more forward. It’s hard to say for sure without seeing the sources.
