I actually thought about doing something like that, or putting a note that I will reply to questions and criticisms/whatever, but if you're just letting me know what you took, I probably won't but know that I saw your comment and am glad you liked the icon. I wasn't even going to ASK people to comment but then I realized if I didn't I'd have no way of tracking what people liked so I could make more. Ironically, it turns out that the icons people seem to like most are the ones that I feel I totally missed the mark on and almost didn't even post because I didn't think anyone would take them. So I'm not sure yet what I'm going to do with that information.
