I love the colors and shapes. I'm not sure how I feel about the lack of focus (or the blurring of the flickering flames) It looks nice, but my eye feels it has nothing to anchor it.
Hot indeed. I realise the out-of-focusness was probably on purpose, but (as a pyrotechnician) I know how beautiful flames are when they are in pin-sharp focus, and this doesn't really work in comparison.
