got rejected for technical issues no specifics given

In addition to Ricky's comments: The picture could also been refused for IP reasons as the gloves box on the wall and the tag on the table contain tradenames and/or logos. Thise need to be edited out. I would edit the whole gloves box out.

BTW: some defects can be corrected with image processing software like Photoshp. I'm always astonished what can be achieved. But rarely, you can correct a bad composition when you can't correct with cropping. 

Hello,

The composition is not very good. You have a dark corner at the top left. The image is a bit underexposed. Make the whites a bit whiter. Also, there is some noise in the image, which can occur when taken at high ISO.

Have a read of this. It's a brief guide on image quality.
