Half

Ok, this one is really really nice, like an abstract-like shot, and with nice contrast between the colours. But I feel like I have to say two things: firstly you should straighten it up, make the lines of the buildings parallel with your border. Go to photoshop and use skew and/or distort to achieve that. You know, it's normal to have such kind of distortion when taking photos with such a lens, but if it's on photos like this, then you should probably correct it.
Secondly, I can't not think that it would be a better photo if the day was sunny and there was a better contrast because of the light, plus the sky would be blue and not white. But you can still make that a bit better in photoshop, play a bit around with curves and brightness/contrast.

You have a good eye for that however, not all people are good at taking abstracts!
