Hi Tony... 
The critic of the art or the art of the critic? 
 
That was already commented here by several artists. 
A controversial subject, since opinions are not facts; for the humanity's good. 
 
I don't care with critics, since naturally I am a, it doesn't affect like this me some miscredit to my work for some friend of the community. 
I already saw bad images being eulogized to the end and fantastic images without any comment. 
Happily the option exists of not being permitted comments and / or punctuation, but as that is optional, the artist should face the fact that if he allowed, you/he/she should accept; but the agreement is another thing. 
The critic is really necessary for amateurs, it helps to perfect our knowledge and our technique. 
What leaves me sad it is to see copied comments, and I think as change of favors, of the type: he commented my last work, I will comment yours, I am like this in peace with all, or then: the more to comment, more comments will receive. 
 
As my works in 3D are pure amusement, one more experience; particularly, I create my images (well done or not) for me and friends that you/they appreciate my style, the rest is profit. 
 
We should remind that to like of something it is very private, and an opinion should be before anything else RESPECTED, but he/she has moments that it is unpleasant to see some works. 
 
It would be interesting to see in the comments the punctuation that the critic gave. 
 
Don't worry about the critics, continue your work, what in fact is very pleasant of appreciating.  
  
hugs
