Photo Rejected for Technical Issues

Both pictures are not well framed. If the idea is to use them as a texture of some kind, then they are unusable.

The first one (0140...) has those disturbing hard shadows. That and the composition makes them unfit for stock. I would also guess that there is a slight out of focus there.

The second picture (035...) is underexposed and out of focus. Those are technical issues.
