Main Protagonist Concept

This is the main character concept I started - still WIP. It is put on hold for now because I have to focus on creating the lab concepts and the idea of the main character has already being established in some sketches I have done earlier, so creating a detailed character concept is not the priority at the moment.

My aim is to start using references when creating concept art so that the concepts can look more realistic like I am doing when creating the characters in 3d.
