Wow, this picture is stunning! Ofcourse I'll give you 5 stars each, and let's tell you why.
It's very original, I've never seen a picture of a hand with 'home' in it, under water. It's such a cool idea!
Technique, five. Great job. Your photo is sharp and the location is amazing: blue water, green plants, good sky and nice light. Maybe the top of your hand is a little bit too overlight / white, but I don't care. The reflection of everything is wonderful, the bokeh is great and I like the composition of the arm.
Impact five! It's a breathtaking picture and you have to look longer then 1 second to it. Perfect!
I was just about to say the EXACT same thing! But just think about the deeper meaning here... if home is where the heart is... then where is the heart? It's in the water, drowned... it's kind of depressing thinking of how your heart can get so low that your home becomes the most depressing thing to you... Sorry, that' was just my interpretation!
