I would LOVE!!!! to help you. I love helping people understand art. However The painting is complete so recording it is impossible. BUT I can offer other options. I can meet with you on AIM and talk you though it LIVE via video chat!!! or do a video explaining my stenciling(which may not be perfect) or possibly do a new painting and record it.
The one on one over AIM I think would be the best option. I could answer questions that way.
