It was the first time I saw one of these last year at the Currumbin Wildlife Sanctuary. This emu is a captive bird and was very used to people approaching it.
Canon 300, 300F4, ISO100, f5.6, 1/250.
Cropped approx 20%, SH, levels and sat adjust. USM.
Looks like big foot! The light is pretty harsh but you managed to keep a lot of detail in the foot. You may be able to tone things down a bit. Love the composition.
