Your figure drawings here were really good! I also wanted to add that by drawing a box for the ribcage / torso area, I was able to better visualize how it connects with the shoulders ( with yours, it's simply a little harder to imagine that connection ).
Since you're just getting back into this, I'd say to try and get used to the overall figure and gesture in it of itself ( understanding the human form at large trumps the knowledge of how the bones specifically look like ). But those are just some thoughts for you.
It would seem you have a natural talent for this, that's why I'm so open with advice for improvement. Good luck to you!
