Very nice choice of colours. Was the smoke done as a brush, which I've never managed or some other way, which ever way the spirals are very effective. My one criticism is that the incense sticks are too straight, and perhaps too small, in the reflection on the vase. I would expect them to curved around the bowl of the vase more, to me it detracts the eye from reading the shape of the vase. Not that I have a vase like that in front of me so I might be completely wrong.
