My 2 cents worth: Critiques should be WIP postings here in the forum where one can get help. Replies to critique requests should be positive and informative, never an attack on that person or their ability (or lack of ability). I have benefitted from the comments of my fellow brycers; Like I did not know about setting up a third terrain as a sea foam material for those island shores. And I found out about the excellent modelling program, "Wings 3D". And the HDRI experiments which promise to make certain class of renderings superb. etc. etc.

Didn't you know that beauty is in the eye of the beholder. That's why eyedrops and rose-colored glasses are needed.
