Wow, it really does look light daylight! I think this image struggles with the horizon line. It's not obeying the rule of thirds, nor is it dissecting the image in half. I think that it would have been a stronger composition if there had been more ground included and less sky, but being a star challenge, I can see why you chose to do it this way. I think voters would have forgiven you for including less of the stars.
this looks like the same location as another persons entry. Did you two shoot together? Australians maybe? :) very nice its a perfect combo of day and night here
Taken slightly to the left of the 'Night Reflections' image by another photographer... I'll assume a school project or something similar and try to score this image on its merits.
I think the day / night dichotomy is the primary interest in this image and as such I don't think you pull that off as well as the other image which captures that more interestingly. Otherwise I think the foreground composition is actually a little more interesting.
