I'm biased as this is a photo of my child, in my chair, on my rug, taken by my fella - but the designer in me, can' t stop picturing this shot blown up 2x life size. I would hang it low on a massive white wall, with the actual chair sat in front. This style is reminiscent of Jakub Dolejs work. Art imitating life.
I'd share a shot of Jakub's here, but their website disclaimer scared me a little. follow the link - he's a real talent.
The point is, don't be afraid to go big, REALLY big with your photographs. A shot like this in a big scale will have incredible impact and tell a personal story. This could be amazing in a contemporary children's room. They like nothing more than to look at photos of themselves and other children, and it answers the wants of the modern grown ups too.
