The title really describes, how I felt, when I first saw this picture up close. It's a great picture, beutifully done... and I also think alot of people can "relate" to it - I know I can. To feel like floating in ones thoughts. The model really shows this feeling, she looks quite relaxed and comfortable.I love the way the light and colours comes in, blue is usually a pretty calming colour and it fits this picture really nice.
I don't really know about the idea. The main plot; person, thought, water... I don't personally think it THAT original, but still I think you've managed to make it your own and to do something new and interesting. The technique is pretty much without flaws. The impact is just great... Vision - A+.
What can I say, but this: Well done.
