Rejected for "technical issues", what do you all think?

I had these photos rejected for "technical issues" and would like some constructive criticism.

DSC07372.jpg - chromatic aberration, the guitar is not in focus and the focus seems to have fallen on the chair instead. Cluttered background

DSC07512.JPG - highlights are too bright and shadows too dark

DSC07528.JPG - depth of field is too shallow causing most of the image to be out of focus 

DSC07664.JPG - artifacts and lack of sharp focus

Zoom in between 100-200% on your images and inspect carefully before uploading which will help you to find the issues.
