We can judge a work on its merits, and really it's not fair to do otherwise. We don't have to be jerks about it, of course, but just because circumstances were difficult does not make the work any better.
The closely allied thing we should avoid is judging a work based on what we think it ought to be. I frequently see, on the internet, critique that boils down to something like 'this candid is a very poor portrait' and 'that portrait is a very poor landscape'. We need to judge a photo based on its own merits, and how well it succeeds at being what it is.
I quite like all the variants of the girl that have been posted here, interestingly. This is, basically, because I like the girl, and she is an ornament to whatever framing you drop her in to.
