Hmm...I've got a few minutes spare before I dive back into bed (it's cold here today) but thought perhaps I should give another view on the whole thing. I don't know if I have given a negative criticism so far. And that's because I truly believe that everything has worth. I'm not a professional...but I am learning every day. And I learn best by concentrating on the things I do best. I would rather post a comment on a photo praising it's use of light or colour, rather than pointing out a negative. In this way, the person will be confident in this use of light/colour and be more likely to enhance the parts of their work that might be otherwise lacking. And I think, perhaps, that it is confidence that is most important for those that might be most in line for criticism...i don't know...slightly abstract thought that one... Hmmm...cold's getting to brain, no doubt. So...back to warmth for a little while longer.
