Eh, I wouldn't feel too bad about it. If it makes you feel any better, I have an image up that's almost a week old with 41 views and no comments. :) Time of the week and time of day have almost as big an impact on views/comments as quality and subject matter. I'd agree with the others who said not to worry about it and just do stuff that makes you happy. SamTherapy's totally right--you can't really predict what the public will like anyway. No sense wasting too much time worrying about it.
