Digital roughs for a sci fi cop drama comic.

Can I get some honest feedback on these pages?

Hello Guys, I have been out of the art/ drawing game for some time and have recently made a solid commitment to put down work everyday. That being said, I am super excited to have found this forum! I have recently been taking several of the HTDC courses with the goal of focusing on and revisiting my fundamentals such as proportion, Anatomy(ironically I teach Anatomy at the college level) as well as shapes, perspective form and space. Below I have attached some of my recent sketches/ studies. Please feel free to comment or critique as my goal is to improve. Thanks!
