The idea is very clever, but there are a couple of things that stop this from being an interesting image for me: the textured white item behind the red box, the blue foreground, and the position of the hand. I closer crop on the upper half would probably have balanced it out more in the absence of more hand to the left side; as it is, it feels like too much hand is missing and too much finger is visible. A white foreground and background (or any colour, but it would look nice if the foreground and background matched) would also have made this feel less like a snapshot - it might also look nice in black and white, or maybe a selective desat with only red showing. Overall, while I think this one could be improved, the idea is very clever, and it does meet the challenge well.
