To be honest, I’ve been overworking myself. I also do this for a living. I’m a character/prop artist for Maya Virtual and I work 40 hours a week. So after doing 3D, I do more 3D 
I’m pretty hardcore (enough to buy a permanent Mari license for myself), but I need a break and some exercise. I’m going to put things down for awhile and come back fresh.
Also, I recently won Sony’s robot challenge contest as well. Right after that I jumped into this one… probably unwise, I needed a breather.
