You captured wonderful detail in the face of this gorilla. You even have some nice catchlights/glow in the eyes. This is a good shot that has vast potential to be a stunning shot just with changing two things. The first is crop - bring us/me closer to your subject. The backdrop does nothing for the composition -draw us in closer to this great primate. I would go for a square crop where the face fills 90 to 95% of the frame. Let your audience really peer into his eyes. Second, I think this could use a bit of levels & curves or contrast adjustment to get some depth to the shadows and highlights in the shot. They seem just a tad flat and I know the black tones could be deeper. |
