I haven't seen any of the comments poster by Tigershark, but otherwise I think the reception here has been undeservedly rough. Why shouldn't he be a professional critic? Trolls say things like "this is all crap" to things that aren't crap, and TS doesn't seem to be in that category. There is nothing wrong with analysing Poser pictures as pictures. Saying "Poser doesn't handle lighting well" is no excuse. If a picture is to be considered a valid artwork, it has to be appreciated by anyone, not just someone who knows the technical basis behind it. Do you think that no-one should be allowed to comment on a singer's performance if they can't themselves sing? A good critic's skill consists in being able to perceive the strengths and weaknesses of an artwork and translate them effectively into words. It is not the same as a mentoring skill, which someone above evidently confused it with. Someone can be an excellent critic and a lousy artist, and vice versa.
