I really like the marbling effect that the deteriorating wall has, but it is kind of boring for a background. I wouldn't remain in the same room as that wall for extended periods of time though. :-)
This would work great as a texture in a picture, but as someone said earlier, kind of boring by itself. Not sure how you could spice it up, but it would certainly do well as it is.
Always a good shot, cement, cracks, and texture. I have a wall shot simply called "The Wall" which is very close to this shot. You know what they say about great minds.........John
