I love #1, the composition and colours.
But the exposure is a bit off in the top right the sky is blown out.
The bottom, although not as big a deal could be lighter to bring out detail.
This exposure problem is not something I deal with so much with my snaps but the landscape photographer have lots of tricks to deal with it. They use graduated filters, or for example taking 3 different exposures and using layers in photoshop (or a DHR program) to bring out the detail.
Number 2 is quite nice but I believe there would have been a better composition for it.
The correct section, I would guess, is Urban Landscape. I skip sections and I’m sure many do, you’ll miss out on the people who might respond by putting these here, these are only still because they are photos :) .
