as you can see from the below picture, i have a problem with the blending in my paintings looking a bit choppy. i get that a little of this is desirable as it adds texture. but as you can see, its a bit much as it is now. how can i fix this?

and yes i know about lowering the opacity, but i can seem to get the smooth results i want with just that. am i now lowering it enough? what about other brush settings?
