This is taken at the volcanic beach at Stokksnes in south-eastern Iceland in February 2015.

He or she proceeded to do an epic face plant, which I found was the standard style of penguin landing.

I took this photo while the football Brazilian team was playing for the world cup, the beaches and the streets were all deserted, everyone was watching the game, it was kind of surrealistic to see this usually crowded beach at sunset completely empty except this kid who was playing in the waves, maybe he couldn't have access to a tv or maybe he just didn't care, anyway he was really enjoying the beach for himself and so did I!
I photographed the woman who finished shellfish fishing in the evening of the day of the flood tide.
