Nice shot... Love wildlife photos...
The only thing I would say is that it would be nice if it were a bit sharper. Can't tell if it's due to this being a crop of a larger shot, or just the jpeg quality, but the deer itself doesn't seem to come out as sharp as it could/should.
I know the light must have been a challenge, but... Next time try to bump the ISO high enough to give you a shutter speed of around 1/120 or 1/250... A 1/30sec shutter at any kind of zoom won't give you a very sharp image. Many use a 2 to 1 rule, twice the shutter speed to zoom length to insure as crisp of a hand-held shot as you can get.
