Hello Andreas,
Quite a frame filler, your hippie... Love those nostrils above the water line and 'menacing' look, very impressive. I also like the positioning of the subject within the frame. POV is superb. Great detail as well as colours and textures, well done Boetie
It's all about the composition and it works very well, very good focus from nostril to ears and the way you have handled the light on both sides of the hippo is excellent. Good shot - I like it.
