Can't praise you enough, dude.
LOVED the art style, the mood you created, and even the plunge into the fantasy-esque style halfway through.
If you twisted my arm hard enough, I would have to say that i think your shift in perspectives would be more clear if you gave a better snese of perspcetive against the backrgrounds. Again, splitting hairs, and only because you seem to care about the quality if you are willing to experiment with new styles.
I'm watching that again after this review. Keep this kind of stuff up, this is awesome.
