I really like on this picture the colourtones- The red inside the clock is doing a good job, without it, the picture might have been not so interesting like it is now. Normally I don't like it when a picture only have one colour but the blue color cast in the B/W makes it works great I like the chosen aperture too, but in the background it is a little bit to grainy to my mind (you might have used ISO 200 or lower) , because the foreground is so clear and sharp and this makes a difference I don't really like- but this is my opinion. In all, I like this shot
I hope you understand what I tried to say, my English is not the best
You are truly a great photographer! I love this image as well. I really like the watch is the center of this show shot and the girl behind is so blurry. For me this could be an advertisement in a magazine to sell those watches. Well done! Just keep shooting!!!!!
