The base of the wall is now gray, which will appear to be stone like the rest of the wall when I finally get to finishing it. Got a tip about my shadows and brought them to be darker and it worked out great.
Oh gosh, I have to get back to shading the rocks on the far wall. It’s going to take forever and will work so lovely when I finally do it. But that’s part of the fun of drawing and painting: finding everything that can be worked on instead of what absolutely needs to be done to put it off as long as possible.
