I have continued to work on the concrete in the negative spaces and have started working on the stone textures...layering graphite with a 2h wood pencil and a 2hb mechanical pencil for those darker details...for darker shadow areas in the concrete I have also layered with 5b wood over 2h and 2hb.
Also selective blending with tissue and a stomp and pulling graphite out with a kneaded erasure, and more layers of graphite until I achieved the look and texture of concrete beneath the rocks.
The dancers are more apparent now in the negative space.
