Your critiquing technique is bad and needs to be improved.



But unlike what you did, I'll tell you HOW you can fix your problems.



First off, offer advice. Don't just say it's bad. Even if the artist already acknowledges that.



For example you could say:

"Instead of black outlines, perhaps add some darker variants of the colors to show a little more contrast. It's more work but it will be rewarding if done correctly!"



The only..."helpful" part of your critique said something about the ears. Otherwise, you need to change your attitude. This critique was very rude.
