Critique is different to criticise! A Critique can be full of praise. You can state why you feel the photo is faultless and explain how it connected with you. You do not have to make comments about how a photo should have been taken differently or how it could have been processing differently. Comments like "Wow, this is one outstanding photograph. I love the colours and the
composition. It reminds me so much of my childhood, growing up on a farm in rural NSW. I wish I could take something like this" is just as relevant and good as any other critique. Just remember that rather than say 'WOW' alone, add why you feel it is a WOW.
