This is the promotional art for our soon-to-be-released game MazeQuest RPG for IOS.
I gave the watercolor paintbrush from Clip Studio Paint a try. Seems to work pretty well, although it functions nothing like watercolor in real life ( more like oil in fact ).
The colors are probably terribly out of whack, I'm going to have to load this on to my laptop to fix the colors since my monitor on this computer is dying a slow death and the colors are really messed up.
