are those a bunch of little ufo's in the sky or is there just some dust on your lens? besides that looks like pretty good, not sure if it was a picture worth freezing your arse over though..
The wind in the trees shows pretty much, if you went for THAT aspect then you were successful. But even your tripod shook, I think. OR you exposed for more than 30 seconds? Then you get the first steps into star trails. Not sure I like THAT effect here.
And why B&W? Did you originally take a colour photo?
