saying that the illustration is amazing would be an understatement. i like your choice to minimize the color pallet into the complements of orange/blue & highs and lows yellow/purple this gives it a lot of pop. also in keeping the warm and cool colors so separated you've give the piece a wonderful sense of depth. the only fault i'm finding in my brief run over of the work is the red square working against the smooth composition. maybe seeing a little red square on the right side of the comp would check it off. cheers, bet it is lovely in person.
