I like your idea for this theme, but, without the title I would not know what I'm looking at. I think the picture itself needs to convey more of the theme. A little more light and clarity would help a lot.
pretty! But long exposure looks very soft and does not include many points of interest. Nice in an abstract way. Points of light on horizon might be distracting to some.
I love this, but I think it would be a ribbon winner if you had straightened it up a bit. I'll give you the benefit of the doubt of not knowing how to do that in photoshop, and give you a 10 anyway. Because I just love it. It reminds me of Tampa, on the causeway over the bay to Clearwater...
