I have indeed got a lot of negative comments on my work, some constructive, some just flat out destructive and insulting (I even have many friends that refuse to read my stuff for various reasons), but they are often much outweighed by the positive response I have gotten from fans that do enjoy my work.
I've gotten many comments such as "I only read this comic so I can eventually watch you inevitably crash and burn" or "You're a lazy artist." "This comic is bad and no one will take it seriously because of -reason-" followed by someone else saying "This comic is only popular because of -same reason- and not REAL talent" I've got reviews that complain about how I don't know what I'm doing, or the characters are boring and have no personality. Even complaints about not having enough fan service in regards to the art. I've had people come into my live streams and complain about my work the whole time they are there, compare me to other artists and flat out tell me I am never going to be as good as -artist or comic name here-
On the other hand to counter all that negative feedback, I've gotten comments such as "Sometimes I'll just have really bad, horrible days, and I come home and see that -comic title- has updated, and then I my day gets better." "Your stories and characters really help me get through things, especially as of late." "You are such a hard working artist, I don't know anyone that works as hard as you, most people in your situation would probably have quit by now. You are an inspiration." "Can you teach me how to do -something related to comics-? I just really like the way you do it." "I love your characters, they're so real and have such personality, I can related to a lot of them. Keep writing good characters." I've had people thanking me for having a character that is or acts or looks a certain way. Which was something I never expected, people THANKING me for creating a character. I even have people HAPPY that my drawings are under sexualized instead of over sexualized, that to them it's just really refreshing. And even for the people that complain that I'm not good enough or will never be as good as other artists, I've also had people tell me that I'm one of their favorite artists.
I've had reviews done on my series by really picky reviewers that seldom have anything positive to say, where they have actually been 'surprisingly impressed' (is usually the way they put it) by my work, I've also have had reviews done on websites that will give my comics a low rating and complain about every detail in it when it's usually a very easily impressed reviewer that will praise a cliche story (even when they know it's cliche) that looks like its art was taken out of one of those how to draw manga books.
And yeah, it sucks getting negative feedback. Even though I know I'm not going to impress everyone and I never set out to really even try to impress anyone, but even in that mind set its still jarring to actually SEE people reacting negatively or to flat out just insult you/your work. Regardless though I just need to remind myself that there are people that also love my work, my series has fans, fans that love it, look forward to updates, comment on almost every page, and even fans that will do fan art, fan fiction, fan dubs, compose music 'inspired' by my work, make video game skins of my characters, animate panels and pages, or just go through the time to send me a comment or PM saying "Thank you for your work" That is the kind of feedback that should be hitting you the hardest (in a positive way) as opposed to the "This is shit. You are shit." type feedback.
