That's what I want to do sooo often! (I think you got comments like this a 100 times.) Great idea! I must say I don't like how you used the ceiling and the curtain in your composition: I would have left out the ceiling and include more of the curtain.
The pink walls make this...something about the softness and femininity of the pink contrasted with the apparent violent act of chucking those damn alarm clocks across the room that makes this quite delightful.
I like this - though normally such wacky set-up shots are the most complete turn-off, there's something about this. Not sure what it is. Could be the sheer blandness of the colours, the cieling tiles, the small net curtain - such truly suburban elements - which give it that aspect of extraordinary moments is absolutely ordinary worlds. Interesting (my highest compliment, perhaps).
sometimes is't just a pity you know how a shot was set up (probably wires on the ceiling). Now I can only see this photo like it was made, because there's not reall movement, I hope you know what I mean. It's too static for me.
Excellent take on the challenge! I'm not normally a fan of set-ups but this tickles me.
I hope you confound expectations and score well, but ultimately it doesn't matter because you've got a good image that's memorable and outside the comfort zone.
