It's alright of course, sometimes you get a large number of comments and you just can't reply to them all. It's sweet of you to take the time to reply to as many as you can though, I thank you for that.
but on a serious note, I can imagine it is overwhelming to get so many comments, and some of them are just "that's pretty" and nothing more. I understand that when an artist doesn't reply back it has nothing to do with me personally, they're just busy.
The most important thing is, I guess, to reply questions and so on c: If there's only somebody who says: "I like this" ...then I can understand every single word you wrote here haha We you anyway you're reacting!
Some artists may be too shy or just not have enough time I figured that I could spend some time answering comments but even I don't have enough time to respond to all of your overwhelming support! but it probably doesn't really matter that much but I find it fun to actually have little chats here and there in comments plus there's always mini discussions that'll give me ideas or people sharing ideas back and forth; I always like that too
