Worked on my wall a little more. Painted it a yellow ocher it might be a little too dark but Ohh well. Added the soot to the blast holes. Put on the vines and added some brown to give it a burned look. Then I hand painted the rebel graffiti, the rebel symbol and the lettering that spells "REBEL".
I know I got carried away with the yellow I'm really thinking of rebuilding the entire thing it was virtually free I have plenty of building supplies. I'm not happy with the color or the archway and a few other things that stick out to me, but its cool it would only take me 2 days or so.
