Sci Fi Model Progress and Predator

I've been working hard on my film quality sci-fi character model. Some weekends I work up to 12 hours on it. Unfortunately, I often find myself spending a majority of that time obsessing over proper workflows in ZBrush or Max and learning best practices and what is the more practical approach for a project like this. I've remodeled and re-sculpted several pieces of the armor. What you see in these test renders are merely half of the parts I've created for the character. I have two more files filled with armor and other parts to add into the master Max file.

I've touched up this Predator painting I did in 2011.
