They are both very good. For "Random gurl", you have got the body proportions pretty much right. I'm taking a guess that maybe hands and faces are a bit more of a challenge for you. If so, then don't worry, most people find those hardest to do - I've know many artists in my time, both professional an amateur, and hands and faces are up there in the top list of "would like to do better"! :) One suggestion is to look for things that cover some of the features, such as mittens and gloves, or have the hand holding something. For faces, shadows cast by hood, or scarves (or dare I say it _facemasks_) can cover/obscure part of the face. These give you practice drawing part of the face or hands. You can reveal more as you wish. Then again, you may have wanted to draw a faceless person with their hands behind their back... You're off to a very good start. Keep at it!

Tbh your better than me!
