I looked around in your gallery uploads before posting this response. I really like some of your compositions that you have posted in there. The ones that I gloss over because they don't interest me are the ones like you presented in your OP. I wouldn't know how to comment on compositions in that brand of photography because it simply does not hold my attendtion, but I can appreciate it for what it is. But compositions as seen in "Them Old Boots", "Sheard Steps", and the "Ohiopyle" series are very pleasing to my eye. But, I believe there is no mistaking it, despite all other satisfying elements, if composition is "perceived" to be weak, then aesthetically, it can fail in any one person's eyes, including your mother's. In the end, if you feel good about it, then who's to say your own perception is wrong?
