Prismacolors and Faber-Castell artist pens (mostly in the upper right section) on 19x24" smooth Bristol paper. Yes, 19x24". They don't have any /smooth/ 18x24" Bristol. Blah, I say. It's like they're trying to make me buy custom frames for $$$$$.
The Prismacolors on smooth paper give the entire thing a different sort of quality, I think; the colors are more smoothed and uniform and blend-y and such.
I like your use of color on this, the bubble with the fish and rain it it is my favorite, but there are lots of good bits to choose from. The black outline really gives it a strength and structure it would other wise lack. keep up the good work
