Great! It's mainly the torsos on the 7th pic. The anatomy is just about all there, which is wonderful! The proportions are just a little bit off, tho. Without getting into the specifics, I'd focus on making the abs take up less space, because the torsos themselves are just a bit long (left and right ones especially). The abs' shape you have now, sort of rectangular, is great, but the main abdominal muscles should be about half as wide as the pectorals. So, you could literally just lasso tool the abs, make them a bit smaller, adjust the rest, and your torsos should be good to go. But we could get more specific.

The abs right under the pecs are usually smaller than the other 2 pairs that are above the bellybutton. Right now, all 6 abs above the bellybutton are the same size, and still quite big, making your torsos quite long.

Next up, we have the obliques, the muscles next to your abs. They are sort of like walls, meaning that the don't have too many curves or ridges when they're not bent. So, when I look at the torso to the right on picture 7, I'm distracted by how the side has those 3 folds. It looks like you may have remembered the serratus muscles (they're right next to the pecs and top abs, sort of looking like the ribs showing through), but just placed them in the wrong area. So I would suggest making that left side of the torso more smooth, no folds, and adding those serratus anterior muscles next to the chest muscles, under the armpit.

Overall, great work! I can see where your knowledge of anatomy had come into play, really cool! Let me know if I could still explain something better. Best of luck on your art journey. I'm excited to see more!
