I'm visiting your blog for the first time, by invitation of a friend who follows you, @velimir. I am impressed with the effect of colors and shapes that you have achieved in this photograph with that close-up approach, if I'm not mistaken. It's hard to pinpoint what it's all about. I think I see a stain produced by a body or substance that has hit or fallen on a glass surface (window or something similar). I notice liquid organic compounds (water, blood...) or of a certain sticky consistency. The effect is almost similar to that of an expanding galaxy or an explosion, which brings to my visual memory certain chromatic effects and shapes presented in "2001: a space odyssey" by Stanley Kubrick. I liked this exercise. Greetings.
