Very nice, it's not exactly similar to what I've made though. I'm still tweaking my depth of field fake. Mine has no scale blur in it though hehehe.
It's no critic, but this is also with a locked focus distance, that's a bit too bad.

Can you get the blur to become even smoother? Now it's quite obvious the objects are getting a 'fur scale blur', not a 2D post-processed blur. I'm sure you'll know what I mean, but here a picture:
