Toyosatomimi no Miko - Art Project (WIP)

Currently is being made on a 16"x20" canvas with acrylic.

I need to figure out a pretty good background because this is turning out a whole lot better than I expected.  I've got values to fix; I'm on point in at least that.  I just need some background color or scene suggestions >.<"

This is also my last piece to turn if for my high school art class.  It's due the last day of school (which is this Friday!).  Also, as a side note, I'll be playing Touhou in engineering class in that same day.   Basically, my last day of school will consist mainly of Touhou, which is so fitting if you know about my background history of Touhou xD
