Looking good !
For the spotted look - Grab an old toothbrush, dip in it the black paint and flick it on the cabinet. Try it first on some cardboard. I usually don't thin the paint, but sometimes I do - depending on if the brush is hard or soft. Trial and error. It will take 30 minutes to have the effect working perfectly, and 2 minutes to do the cabinet. Make sure you do the speckle straight after the base. Don't so any stenciling beforehand.
