I like week one, would like to see a bit more background to show it really is snow, but it is a great idea and concept and well-taken too.
Week two, nice and bright, love the poem too.
Week three is oddly bw and I am not sure why. I realise there would not have been much colour there anyway but that, to me, is why you should have left it in? Great idea again but like week one maybe a bit of a tight crop for my taste...
