Rainbow Rocks

Drawn 11 years ago by Papachan for the Draw anything you can challenge and inspired by Color mixing doohickey.

This is a lot complicated in filling, I started this drawing around 7:30AM PST, it took me at least 1 1/2 hours to complete it, The hard part about it is filling in the rocks. No need to complain about this and this is one of most important drawing I like!, my opinion.
