Hi Roxanne,
I've been watching this 30 day of ordinary objects, and some of the most interesting images came from you. Congrats for another great photo.
(this is a potencial photo for a great concept ;)
They turn purple? Interesting. I like the landscape version with the bottle pointing sideways I think. The bottle on it's side is a bit more unique than pointing upwards, yet it gives a little extra space.
Actually that's not quite what I was suggesting. Here is a really rough example of what I was thinking of. I do like your flipping to landscape though compared to the original.
