Whilst most of us don't claim to be perfect in what we do, what little imperfections do you see in images that with a little work, thought and effort could be altered to improve the image .
One of my pet dislikes is crumpled material backgrounds, which are more often than not just an old sheet. Sorry this makes the images look really tacky and irritates me almost as much as BLBP (which there seems to have been an abundance of in recent uploads ).
