no one can tell you what is the perfect thing to draw for you. You will find it if you continue to make art. (i know i have)
but with suggestions on your peice, use a value scale. You need darker darks , whiter highlights and more values in between. Try that using layering getting daker in the right areas with each layer and using a eraser to get some highlights. Good Luck raw
I agree, and go to Artschool, you'll love it... Mitchell Foley
