I'll only comment on things I really like or if a see something that can be improved on an image that grabs my attention in the thumbnail gallery. Don't feel bad, my best image has gotten a mere 196 views with maybe 3 comments while another has only gotten under 100 with 5 comments. As said above just do what you want and if you are working on an image post it hereand you'll get some comments on how to improve it.
