Practice, practice, practice! Use a larger brush than you think you should. I know myself and a lot of people I see starting out use real tiny brushes. Work large to medium to small!
VidGameDude: Dont give up though. Practice practice practice. For me, learning Maya was nowhere near a liniar curve. Alot of things just begang falling into place when you finally feel comfortable in a 3D package
hands are really tough. this is one of my hands, which is far from great, but has a lot more structure/detail my advice is just keep on practicing as they are quite tough, make you go insane :) I use the dam standard quite a lot to kind of sketch out the details
for the rest of the day adding in the intro cinematic and get the rest of the player camera system working in practice with E1M1. https://youtu.be/eJUy_zZl-Rc
