Not a bad start. Definitely an improvement over the other I actually used a soft brush for the entire thing I believe. For hard edges you can just make the brush smaller. You can do the same if the lasso tool isn't good for you. I recommend practicing using the lasso tool because it can speed things up in my opinion but its up to you. Its not needed though.
For this new version I think you should work on the values. The contrast of things are to close to eachother. Heres another PO to help
I didn't work on every area. Just the arm that's raised up and a little bit of the face. Here some ref similar to what you have so you can visually see what I used and how I applied it.
