Hi Colin.
Effort - Cool piece of PP there, definitely a goof effort.
Technology - Not sure I'd be trusting my wine to that, but an interesting piece no the less.
Horizontal - Yes, I can see what you're aiming for. Also, interesting colour to the light that has shone through the window onto the wall.
Vast - On theme, but for me a little lacking in contrast (try playing with the black and white points if you have the raw). I think that the Dutch angle does work though.
