Looks pretty good to me; maybe play with the WB... to tone down the orange 'cast' on the boat?
But the pic exhibits the typical qualities of a night shot taken when there's little or no light left in the sky: very contrasty, with dense, black shadows and pinpricks of (burnt-out) white lights. If you took the same shot during the hour (or so) after sunset, you'd still have the atmosphere of a night shot, but with a whole load of extra ingredients to play with. There wouldn't be that stark contrast between shadow and light; there would be so many many shades in between. Colour in the sky would reflect on the water, infiltrating - and opening up - the shadows. The orange cast wouldn't dominate; the 'warmth' would be more natural, not man-made (ie from sources of artificial light), the colours deeper, richer. The balance would change, minute by minute, between the natural, ambient light and the artificial light. The scene would really start to 'sing', become less static, more dynamic... and all this would show in the pic.
A great exercise would be to set your camera up a few minutes after sunset, and, monitoring the way post-sunset light keeps changing, shoot pix every five minutes for the next hour. You'll find, later on, that one or two pix will have captured that balance between light sources. It can be a magic moment, at the time of shooting, and another magic moment when you review the pictures, back home on your computer...
Thanks for the observations. I didn't notice the bug until I got it into post. If I had, I would have shooed it away. Bug on flower is a cliche. Personally, I don't like the leaf intruding from the left over the flower petals. Thanks for reminding me that the white balance target I carry in my bag is a reflector, too. One of the things I like about exchanges like this is that they really do make me think more about my photography.
'Bug on flower' a cliché? Tell that to the bug; it may be his finest hour...
Since everyone has a camera these days (plus a few more... in their phones, iPods, hairbrush), most subjects are photographed again and again and again. A cat, a flower, a sunset. I don't know if that makes them a cliché; the clichéd aspect may have more to do with shooting the same shot that's been taken so many times before, in the same old way... rather than looking with 'fresh eyes'.
There are lots of flower pix on PotD. Most of them make me glaze over a bit... and then one will appear that really makes me go "wow!" And it won't have been taken with special gear... just a special eye, looking at something that everyone photographs every day (yawn...) and yet sees something entirely fresh and new. This shot's OK, for me, but it doesn't give me that feeling that I'm seeing something for the first time.
