I am hooked on you're work, love your style, and this piece is no exception. The slight elevations across flat hard surfaces is something you pull off so well; do you mask off areas for such an affect?
Thanks for your replies ! @tottot/chris : I used an alpha from one of my sculpt to do these slight elevations. In this way, I can control the intensity of details. I used the mallet fast 2 brush and the flatten brush to do this alpha. Sometimes I can use a mask to define my general form. I added more color variations :
