Thanks Areinu! I was really afraid of not daily updating the asset and I ignored my forearm and wrist need to rest, I feel really dumb now. I need to change my habits and my hobbies cause the thing I want more than ever is to keep working as a Game Artist. The vertical mouse is helping a lot, even if I won't be able to draw with it cause it's really imprecise compared to my classic mouse, but I'm gonna use whenever I can!
Wrist update: I'm almost ready to start drawing again! I've tried drawing a bit during the last days and my wrist is getting better and better, even if it still hurts after a while!
