The tones in these are absolutely stunning; the contrast and clarity are magnificent. I think buildings are difficult to photograph, so you get extra points from me for that one too :) You do have some that need slight rotation though, as was said; this is only true for some of them that are more straight-out building shots than creatively angled ones.. an example would be the Escolta image, which needs a little rotation to even the horizon out :)
As for the colour ones.. Party Time is awesome :) Nice work.
