I like pretty much all your stuff, but this one in particular is great.
In terms of focal length, well, I've always used 18-55's in the past on crop sensors. Going to take a look through the library and see what length I've most used but i think it'll be closer to the 35mm than 23mm. Does anyone know an easy was of finding this out in Lightroom?
Looks like you can get the 35mm for some great prices second hand too.
