I use paintstorm for fashion illustration. Line weight according to pressure is really important to me but I feel like my strokes are coming out very even.

Currently using the clean art brush - tried adjusting the pressure but can't figure out the right combination. any help/advice?

Also any other brushes/tricks good for fashion sketching lines is great. mostly looking to recreate pencil lines and flicks.

A very abstract question. Attach screenshots: what's you need? What's you get?

basically, i loose weight depth when i switch to a thinner brush. maybe there isn't a solution. i just would really like my strokes to feel more dynamic and am not sure what else to do.
