Japanese Waterfall Tattoo (Sketch)

   My friend Mark requested a rough sketch of a tattoo idea he has for his back! He says the idea of a Japanese waterfall came to him in a dream! Even though I'm not entirely sure his idea will work for a tattoo, (there will be soo much detail and I imagine it will take forever to have done!) this was still fun to sketch out. If he wants me to refine the idea more I definitely won't mind working on it further. These are scans from my sketchbook.
