I completely agree with both of these statements.
For the audio you might want to go out and buy or just make a simple pop filter out of pantyhose, it will fix the peaks and blowing with ease.
Also I too was wondering who was talking, being able to put a face to the voice is a big plus because it gives the viewer some relativity.
Some really nice shots in there though, very decent edit for your first time doing something like this, keep it up!
