Male Body Sketches

Hello Darlings!

This is a little different from my other posts. I have struggled with the male body and always felt uncomfortable drawing shirtless men. However, I pushed that aside and challenged myself to draw three men of different body types and since I am a huge nerd, my friends and family suggested I start with people that I have seen, ie, superheroes! I decided to go with Chris Hemsworth's Thor, Jason Momoa's Aquaman, and Andrew Garfield's Spider-Man. I plan to do more maybe on a later date, but for now I am very happy with how they turned out. I am more confident with the male body now that I did these sketches and have a better understanding on how the male body works.
What are your opinions on these sketches?
