nice to see you pushing things to finish man! don't use so much black to shade things though! not everything gets black if it doesn't receive some direct light, there's some ambient light in most situations and lots of materials wll still be light even in shade. remember, halfway to black - if it's a 100 (white) in light, it'll be around a 50 (grey) in shade. not always obviously but a good rule of thumb to start with. post studies!
