Does constructive critic really works?

[Madzia]

... the guys here are a bunch of kittens compared to the scathing crits some people back then would give...

Yeah, I know worst places where others would just stab you with enjoyment xD

Alot of begining artists have very thin skin about their work. but critique is invaluable, you cant see whats wrong with your work alot of the time ...

In part I agree with you but it's not necessarily to make progress. That depends on personality a lot, if you are disciplined, know how to find good resources and maintain studying and drawing you will get the same result. My friend tried to convince me that I will never achieve anything If I close myself in closet. But I made huge progress on my own. My self hatred is really big xD And my inside criticism was pushing me forward all the time.

I'm of the opinion that harsh critique is good, especially for someone looking to get into any sort of work where your work is judged by a boss or client, they will tell you if it looks like shit. Hell if I'm critiquing someones work and I notice something off I will say it, and usually its pretty blunt because thats how I learnt, and I prefer people who critique my work don't hold back, why? Because if theyre busy trying to protect my feelings theyre not helping me learn.

That worries me a little. You should be honest, especially if it's work for money and you expect certain level of quality. At the same time if you work with other artists You need to care about their feeling, otherwise everyone will get so stressed, start to hate you, hate job and never give their best because their motivation is gone.

It's freaking hard to get this shit together and make good conclusions. If we assume the artist is high motivated person willing to learn then constructive critique will benefit him. Because he/she is his own boss and know how much he can demand from self. He can filter informations and choose with one are important.

But if that depends on someone else and if the artist is not self confident and with every next feedback he begin to feel he's not going to meet the requirement of quality. He will start to feel helplessly.
If you where a friend to this person, or worst if you where his leader and you're seeing what's going on, what would you do? Shout him in face how much he's behind and he need to catch up fast, or try to be polite?
