Hi Chuck,
I really like the second one, it is a very pleasing abstract and very much the sort of thing I like to look at. The first one slightly less interesting and it looks a bit too crunchy and over sharpened to me. The third one has something, but I find the top right hand corner very distracting, it sort of lets you slide out of the picture, and the wide undefined shadows bottom left don't help I'm afraid - my advice should you wish to take it, is to always try to fill the frame with your subject, but first you have to decide what your subject is, however abstract it might be, then having done so, frame the shot but always pay special attention to the corners and try to avoid corner triangles if possible.
So I think #2 is a winner and is a great example of what can be done when you look for it, #1 is a near miss whereby the PP is a bit too much and has become distracting and I think #3 is a miss unfortunately - for me at least.
Dave
