Great concept, but too many little irregularities (uneven texturing on the foreground wall, cupboard door partly open, curious shadow in far corner, marks (?) on ceiling). Really great idea, though, & your choice of white on white is very effective.
I sat for ages looking at this pic and got to thinking what could be creeping out that cupboard door lol this is a really nice shot, love the composition, but the only thing that puts me off slightly, is the cracks around the wall.
