Rejected fotos

The first image is underexposed and poorly framed, with the blown out upper corner and fence post intruding on the lower right edge. The second image is interesting, but you've missed the mark on both focus and composition. The refracted image inside the crystal ball needs to be in very sharp focus. Use a tripod. Stop down the lens (higher f-stop) so that the guitar is more recognizable in the background, and look for a lighting scenario that doesn't result in large white blown-out blobs throughout the image.
