I'm all for criticism. It really does help us grow in our different creative venues. I started posting art and literature on the internet at a young age, so I learned to develop a thick skin and learn to differentiate between what were insults and what were critiques. Sometimes they're very obvious, but some not so much.
I requested a review on my first webcomic-turned-published-comic way back in the day with the original art, and original chapters so it was a mess to begin with because I wasn't very good at storytelling at the time. I knew it was a mess but I was interested in someone's honest opinion rather than "omg this is cool!" (which these comments do help with motivation, but don't help me GROW into a skilled artist/storyteller). This reviewer was harsh, they bluntly laid it out on which pages were a mess, how sloppy the art was, and how broken the grammar was. And let me tell you, it was a serious wake up call. I didn't take any offense to their review, I wanted their help and I was also very humbled they also highlighted the parts they enjoyed such as the plot, the design of the website, and the art that improved from the 2-4th chapters. It was a very much needed slap in the face, and I'm STILL grateful they ripped my comic to shreds (in a good way of course!). So, I went back to the drawing board and restarted completely: on the art, dialogue, paneling, etc...I didn't form it to fit their specific tastes but I did change it to where it was a more cohesive story. And honestly, without their review I probably would've never have gotten a publisher to pick it up.
On the other hand I have gotten insults like "this sucks" to which I ignore or depending on my mood, I'll kill them with kindness and say "I'm sorry you didnt like it, but thank you so much for reading it!"
And I have gotten comments like "The lighting is a mess" or "You need to redo this picture." I consider these half-critiques, to which I reply to them, "Thank you so much for taking the time to look at it. Do you have any tips or tricks on how I could improve?" And these replies I make to these specific kind of half-critiques I'm always sincere. Though sadly, most of the time they don't respond :/
