Childishly simple that didn't even work out well. That blue is cyan and that orange almost a brown. Serious cropping should also be done to get rid of all that white.
I played around with this concept, too, I actually have an old picture that I took a while ago with crayons and colored pencils like this, I think it works really well for this challenge
nice idea, although i would have chosen a different composition, maybe use more negative space to the right. also, could have bumped up the saturation of the colors
