hmmm.... where to start....
this photo is very unique. the wispy smoke makes it look sort of mysterious and alive- it makes look like it is not smoke at all, but a soft fire. a nice touch. also i like how it is clear, and the back round blurry.
the red glow from the incense makes you want to keep looking at it.
plus, you did very well in finding the good pose, and having the lighting come from one side. as i said before, it is mysterious- and i just realized the dark back round. it makes the watcher always keeping his\her eyes on the incense.
