Scifi Drone Concept - Helmet

I started a new character concept. This will be a character where I'll be exploring methods and workflows, so there will be plenty of mistakes on the way, but I hope to learn a lot during this process. I started with a really rough sculpt of the character, separated head for refinement and then added details. I did a quick material render using Octane Render, The model still needs to be UV mapped, but I'll wait till I finish the rest of the body.
