This person needs to grow up. Everyone is entitled to their own opinion but using such a hateful method to express it is just juvenile. And with a comment like this: "You always say that your drawings are bad, even though you know they aren't" I seriously doubt that the person hates your work. Maybe jealous? Frustrated? idek.

Re: twincest, lol. I can't judge, I was in HP fandom for a long time, ha ha, I know all about that stuff. Write whatever you want, bb, it's called fanfiction for a reason. :)

Hope this guy didn't make you too upset. It's great to see you addressing it in the open like this though. Be strong! ♥
