Nice, @Anubhav Saini! I like the underlying gestures and how you’ve indicated the placement of some bony landmarks such as the spine of the scapula, the rib cage and the clavicles. As I’ve commented previously in other posts, I’d encourage you to explore more of this underlying bone structure in order to find the origins and insertions of the muscles as accurately as possible. For the Deltoids, I think it would be essential to sketch in the Humerus too. Also, try to consider each model's physique and body type - for example, Anthony (upper left) is very bulky, so you could make the muscles have really noticeable 3D volume. Yoni (upper right) is muscular too, but has a bit less definition, so you could experiment softening some edges, maybe even blending the forms a little bit. As for Laura (bottom left), who is very lean, you can try making the muscles thinner and less volumetric, yet defined. Other than that, I think it’s pretty much what @Steve Lenze properly pointed out already. Hope this helps! Ah, and I like how you’ve organized you references and drawings in this image, it makes it a lot easier for us to look through and comment! Thanks!

Hey Anubhav, Nice job on these. One of the things I noticed is that your drawing the deltoid muscles very puffy and round. Remember, the muscle will flex and bunch up on one side, and then stretch and straighten on the other. I find that it also helps to think about what each head of the muscle does. I did a couple of sketches to show what I mean, hope it helps :)
