Love the tree and the scene. Shot is very over-sharpened though. Tones are quite rich but a little too harsh for true AA. The sharpening coupled with the many branches visible makes this very busy to look at. OK composition but the tree cropped at the top is a shame and eye-level POV is quite bland.
To improve this I would have got closer and looked upwards from a low vantage point. This would show more detail, add some drama and, if you were to expose right, get a long DOF which is very typical of AA.
This is a pretty clear shot of your subject. I think, for me, it's lacking in tone a bit. There doesn't appear to me to be much variation in the b/w scale compared to some of the other shots. Also, I think the subject and composition are hurt by all the branches and other wood in the foreground and in back of the subject. I hope this is helpful.
The sky is the missing piece in this photo in my newbie estimation. Clouds would have given this photo the push to the realm of wonder. Still, I love the contrasting blacks/whites of this tree in snow. Beautiful work!
