Cursory comments - the intro was too long in my opinion...your title should come faster. Furthermore the entire reel was far too long. From what i've read and seen in the forum so far, the best reels are between 1 to 2 minutes long, and you should put all your best footage in the first 30 seconds because most people watching your reel would stop after the first 30 seconds if its unimpressive.
I felt your reel really picked up towards the end, and there was some nice footage and camerawork. I especially like your 'technicolor' look. There was some neat editing too for some of the nature shots, namely the storm shots. However, like i said it was far too long to be a good reel. There is alot of potential in there for a great reel, except for the length of it. Now i understand that this is just a test reel, and my comments are just assuming that you would want to develop this into your 'real' reel. Other than that there was alot of nice footage in it!
