That piece leaves me somehow with an unconfortable feeling. At first, the cuteness of the scene makes you smile... Then, you see the blood from his heart flowing through his fingers and on his shirt... and still you smile... until you try to find out why his heart is bleeding... That unconfortable feeling, that cheerful sadness that flows through me, is such I can't stop staring at the scene. I think the composition is brilliant. All the elements just... flow... like a bloody birthday song. Weird... but still: Great job !
