Good choice of the foreground in #3. Perhaps you just need some extra light to make the scene shine.
Photo 3 is taking my breath away!
And there I was just starting to look at this thread, and already thought upon seeing Photo 1 "Wow, this is nice, what a wonderful time of day he chose to take these, the sky still bright enough to light up the scene and have lots of detail both in the sky itself and on the beach, yet so many lights already on in the houses and in the streets", and then I came to Photo 3 and could only gasp! This is so much "Blue Hour", and I LOVE the "Blue Hour" ... I am all in love with this photo!
Is Photo 1 an HDR, by the way?
