I had a friend on skype ask me this before because as the statistics on this site and others show: I comment and fave more than I receive in turn. My answer to them? If they like my art enough to fave and comment good, if they don't all the more power to them. I draw for myself to make me happy and even if I'm going through a rough patch with my art right now it still makes me happy.
Yes I would LOVE some acknowledgement that at least one or two like my work but I don't expect it. Because I'm going to be honest I think the most views I get on my art is possibly 10? and I know a couple are me when I'm checking to make sure I didn't screw up a setting or a tag. Or to see how many views it got -shrug- But it doesn't bother me, I'm not a popufur like most of the people around,I don't have a stand out style, or a cookie cutter style, and my art is mediocre at best and I'm continually trying to improve. So I don't really expect a whole lot of people to do more than a 'okay lets look at this, ah okay, next picture' which is generally what most likely happens.
tl;dr version: Yes I would love more comments and fave and some interaction but it doesn't bother me as much as it should possibly depending on other people's views about it.
