you have a great understanding of anatomy, which is especially seen in the second image :) i think your forms are great and really expressive and you can try experimenting with lighting or even color!! keep up the good work
these are really good your gestures are amazing!!! i see in day 2 youve started to put more detail into lighting so i think continuing to build shadows + highlights will really bring your pieces to life :) remember not to be afraid put darker shadows, try to mimic the tones you see in the reference
