Very nice pictures, ACH, and I'm surprised you got them looking so natural with that lens - I'd have imagined more distortion. I was never an arch. photographer though I did shoot some house stuff for holiday brochures and estate agents (just a bit!) now and again, but always found myself frustrated by lack of movements - hated cropping at the wrong levels, but knew no other way of staying vertical... no PS in those days.
Colour looks very inviting, to me, and that's what usually counts, I'd think: attractive versions of reality.
