Verrrrry Gooood for a "first attempt"! (Really???). Your camera moves looked very good and generally very smooth. There is a moment at the 1:07-1:11 shooting the barge Kamikani where the camera takes a rise followed by dip then follows the side of the barge. That was a little distracting so you might want to cut about 2 secs from the first part of that clip to eliminate that and that will "smooth out" the rest of the pan.
It was very impressive and my bet is that the folks at work were quite pleased. Keep up the good work. Happy Landings.
