Too much? I think so. I could go hog wild with the colors on a smaller, less complicated painting but I estimate the finished piece planned will be approx. 15" x 10" (at least) so all these colors would probably be overwhelming . I had to try, though. I also discovered I need supplies, mostly more Micron pens, so I put in an order last night. I'll have plenty of time to play some more while I wait for them to arrive.
