Fantastic. Creatively constructed! Inspirational!
From a cinematographical perspective this is possibly the best work I've ever seen on newgrounds. Dramatic music coupled with a slow but heavy crescendo made this genuinely rousing without the need for graphic violence (I appreciate that it is actually violent (before I get flamed over and over :P))
I'm not really sure how I feel about the subject matter but I do agree with an earlier review about portraying the feelings of the japanese... But at least your definition of the events brings a slice of originality to the hiroshima bombing genre.
With regards to the artwork, some of your drawings are fantastic given the limitations of not just flash but of vector art in general.
Congratulations on a fantastic animation and the well deserved recognition you have gained 10/10, 5/5! Keep it up!
