Flow is really nice like you say it is simple but nice work i would give it a 7 but only because of simplicity if it had some cool effects in it i can see it being a 9 or 10
Definitely a good piece. Did you skew the render/stock? If you did, very nice usage of that technique. I've never seen it pulled off before. Like the simplicity. Good work
the simplicity is nice and all but its a bit too simple imo, a bit more extras woulda been nice, not bad though
