lol master ',:D

umm i feel.. important now Sub for you, anyways, the top of the shoulders are facing the wrong way, and when you shade, what you did was right, but you should add on to that, like make the nose area a little bit more noticeable, or add shading where there would be wrinkles (like cheeks, crows feet, etc), or some wrinkles in the shirt, and like how the sleeves/shirt overlap things (like wizard sleeves, or baggy shirt areas), try to add shading there like add some shade to the area being overlapped, then the same thing but a bit less dark and ont section away from the first one, lastly, i like to copy images from google (screw bing it doesnt have good pictures) and paste them then use the turkey baster to get some colors from the image (i noticed when i use color wheel colors im usually way off). hope i helped, and this is a good skin btw, the more you make skins/mess with the program you use the better you get. (the last part after i hope i helped sounds kind of like i think im all that, but its true, also im happy you asked me for help, i find myself decent, but not a master lol)
