Les, I just looked at your gallery and I see that you have some outstanding work! So it's not that your photography is lacking! Personally, I like these kind of photos, simple and almost abstract, but you will find that the audience for these shots is not as great as say, waterfall shots or animals.
And as Fred said, factors like the time of day and even day of the week can effect the amount of comments.
I don't play the popularity game, so I really don't attach any significance to the amount of comments on my photos. I try to comment on others when I can, but with time shortages, I can't always look at everyones work. It's a shame that the system works that way on this site. Don't take it personally.
