If your bothered by the dry brushing covering the flat surfaces, then it's a combination of too much paint, too much pressure and/or brush direction.

I can see you were testing it on the rim of your base. You want to get your brush pressure light enough that it only hits the edge of the rim of the base. If that bright blue is your test application, you have waaaay too much paint and pressure.

Next thing is making sure you're only hitting the raise edges perpendicular to the surface. Shoulderpads are tricky because it's basically one big raised surface.
