First off, I'd like to state that I admire your style. It's very original, and I feel like I've never really seen it before. The anatomy looks well done, while still fitting in with your style. The most impressive trait about this drawing is the coloring. Despite the fact that you merely photographed this, the shading allows the colors to really pop and makes the drawing stand out.
My only suggestion would be to shade the males hand a little better because in comparison, it looks a little flat. However, the shading may have just been lost with the darkness of the photo.
