Very odd compression-like artifacts. Was this a picture taken of a bad printout? A neat idea, but the quality of the digital photo seems to really detract from the idea.
Has a weird sensation of not being absolutely symmetrical ... just enough to make it slightly unsettling to look at, like there's some distortion somewhere. Colour saturation hasn't been dealt with terribly well, lots of pixelation in the pinks around the brightest areas. Jaggedness from perhaps over-sharpening on the hard lines too. All that said, it has potential as a geometric image i think, but too many things interrupt the cleanness of the presentation for me. 4
This is an interesting composition and nicely toned. But, it is suffering from a lot of jpeg artifacts (like the jagged diagonal lines and the jarring color gradient on the sphere). Try saving with a higher quality setting (this picture only uses 53k and you're allowed up to 150k for your entries).
Meets the challenge beautifully, only thing I wish is that you would have taken the photo at a straight angle, so that the top line of the square would be level instead of skewed. The jaggies on the right and left of the square are probably more a result of the jpg compression, but still wish they weren't there.
