I have nothing against you. I grade avatars on a very high scale, which means that my standards have something against you, not my personal opinion. I'm not a spiteful person to those in which it's not my place to be spiteful towards.
I do, however, feel that spite because your feelings are hurt is something that is not very becoming. As I've learned from fiction reviews, you should be honored that somebody took the time to evaluate your work and tell you what they think. Besides, if it wasn't me, it would be the next person.
I advise you to remember what I've said here, and think about how the next person you feel has a beef with you might not be so level headed. Food for thought, that's all I'm saying.
