Make sure you don't have quick draw enabled, and make sure brush 2 is toggled on and brush 1 off, and to get maximum detail set the brush 2 size smaller but the smaller you set it the longer its gonna draw. Also sent a picture of how it should look like, the brush 2 size is completely your choice.
Also the v 0.2.0 is Almost out, its faster, way more optimized and looks better.
