I completely agree! How can anyone improve if all they get is "you're amazing and put so much hard work into this, it's amazing!" when they require an opinion. I'll give you a simple and easy analogy. Think of fanfiction, especially on Wattpad. Some fanfics are so bad and poorly written, but you still see comments from people who say "omg this story is so funny and amazing!" "Keep up the good work!" "don't stress yourself too much and go at your own pace!". These things are similar t what you've just said. And with those kinds of comments, the authors of those bad fanfics won't understand just how bad their writing is. It's not rude or insulting to state the truth. The truth will always be the truth, whether it's something you want to hear or not. And hard work doesn't mean anything either. Have you seen fanart? Especially of controversial ships?? People draw so well and spend ages on it, yet the art they've produced is disgusting, immoral and wrong.
