Interior design in a public place was really challenging. Manouvering your way around people/trolleys/kids and trying to remain moderately inconspicuous photographing inatimate objects with a giant SLR is kind of hard.
I've produced some abstract pictures. My vertical panorama however did not work out, which I didn't realise till I got home, but there was too much lens flare from the sky light which I didn't see on screen on my camera and only discovered when I got home to merge my images.
I think if I were to go back I would take a different approach... and a tripod.
