Does constructive critic really works?

[Vandall]

Again its not about being a bastard, but its also not about sugar coating it. And critique isnt there for motiviation, if it does motivate you, good. But its there to point out flaws in your work that you should focus on fixing that you would not have seen yourself because almost every artist needs fresh eyes to see the mistakes theyve made, without that youd improve very slowly upon your unseen mistake.

Im also of the belief to be a successful artist you should grow a thick skin about your art work. Value your time and work but dont be so defensive about each piece youre blinded to your own mistakes.
