Laocoon sculpt WIP

Hello, I realised I haven't posted in awhile so here's something I've been workingn on recently. I am enjoying the sculpting project a lot and it's feels fresh and different to sculpt a character who's already in a pose.

This is still a very early work-in-progress image, and critiques are most welcome on the anatomy and muscles. I am aware of positioning errors such as his left hand (our right) not in the right angle. The head is a separate file so I photoshopped it onto the body.
