|Greetings from the Critique Club!
First impression: Love the combination of elements here...the shape of the arches, the blur, yet lot of in-focus areas, and a human element to boot. Very good combination. Gave you a 6 in voting.
Artistic: I think the fact that you were able to get all of the above at such a slow shutter speed speaks a lot for your skill and knowledge of your gear and furthermore, good use of same. It makes a pleasing image
Technical: The lighting in the fg is a bit flat but that's all you had to work with, but that's made up for by the bg light through the structure. The comp isn't outstanding but again, the combination of what you caught does a lot more for me than the boring nitpicky details :-) I agree with Deb (Melethia) that b/w might work a bit better. B/W is the fallback for those days when you have crappy lighting like this and drab tones to work with.
Overall: Very good first entry here, 5.6 is a nice solid base to start from! Please keep up the good work, keep entering challenges and keep on shooting.
Feel free to PM me,
