I can't figure out how you decided to crop this picture. I'm guessing there was something just above the head you wanted to exclude badly. I find this cropping to be much too distracting. I wonder what he(or she?) looks like. The colors is great though.
Colors indeed. I'm not sure I'd consider this to be meeting the challenge as it's not really a color on a background of the same color as much as it's just every color and pattern imaginable, everywhere.
From a technical standpoint, this feels something like a crop of a snapshot. The sides have been trimmed very close to the arms, but a spare arm is left in the background. And...the head! Kind of an awkard place to chop off the photo.
