I love how you've written this, and how you have described it all so clearly. 'So everything's blue/From my mood to your eyes' is a brilliant line! I also love the way you describe 'The idealised image' of someone, and I think that you've written it in such a perfectly honest and precise way that a lot of people could relate to it and understand it. Though this is a sad poem, it's still a very beautiful one, and I think its quiet sadness really amplifies its beauty!
