really creative idea and perfectly executed.
i think it deserves a top 10, if not even a ribbon
mmmh only one little detail: normally the order of the colors goes from yellow over orange, red, purple and blue to green, so the yellow crayon should have been on the right, then to the left of it the orange crayon, then the red one, the cyan one, then the (darker) blue one and on the left the green one.
Quite clever. This image works very well for the challenge. Couple of minor items: would have been nice if the white bg could have stayed clean except for the drawn lines, and the lighting is a little harsh on the pencils - did you try to diffuse the lighting some?
I find this shot interesting. However, the angles don't work for me. It would have given it more pop if the drawn lines were fanned out more, and the each pencil were lined up with it's own color. Kinda like as if the line were projecting out from the tip.
I really like the idea but the pencils looks a bit oversharpened. I think without the oversharpening and the artifacts on the right hand side, this photo would have been much stronger.
