Hmmm, I won't really say texture don't make sense on paper, if done the right way texture helps put out the form of a shape, on paper drawing the whole texture observed from a reference something tends to make the drawing looks rough and make it like drawing just random lines to solve this it's important to know when to stop, draw in the important cast shadows. Trust me I do this myself, for instance am doing studies of a tree, rock, ancient Greek or Egypt buildings, there's lots of cast shadows and form lines running around this stuffs and it's filled with them.

I start studying the reference and drawing every line on the rock, get obsessed with the thing at the end of the day I end up with a form filled with haphazard lines, no focal points and no place for the eye to rest. Anyway I really love your submissions especially the wheel challenge, it's really awesome, keep it up
