This is very interesting, the thumbnail being more interesting then the full size. I expected a shaper photo since all the pencil are equally away from the lens, maybe it's just my eyes, maybe it's your lens, maybe it's wrong use of editing software... Not sure. Despite of the sharpness, I like it and gave it a 7.
It does have the colors of the rainbow and it is nicely shot but I'm sure you could have come up with a better subject. This has been shot many times before and it's getting boring.
BTW I would have sharpened all the tips to make it a little better.
