So I made this environment sketch of rocks pointing into the sky, but I'm stuck somehow like in many similar sketches. My problem is that I don't now how to refine the rocks, so that they still pop from the rocks being farther away. Do I pick the grey from the next 'layer' or the layey after the next? Or just harsh rim lighting?
Additionaly, as I want to color the sketch I fail at painting the right colors to maintain a nice mood. Do I make those rocks brownish, greenish? Or should I just throw in a fill-in layer with a tone which suits my purpose?
If somebody wants to do a paint over, pleeeeeease don't hesitate
