I agree w/ Avery, this is really beautiful, but so disturbing. By the first glance and the title alltogether, you get a nice image in the head, a beautiful firework on dark sky an isolated place. But then you notice the birds and the boy with gasoline. I love the use of lightning and the way you use the paint stroking.
Definitely disturbing, in a more visceral way that gore or the like can be. My first thought was "oh, it's metaphorical", and then I noticed the gasoline . . . I think the reason it's so jarring is that contrast between the beauty of the fire and the disturbing story that unfolds. An audience automatically does a little leg work, and we walk ourselves into some very dark places.
