Fun video, some nice effects in there.
Work on your trim and your weighting. If not too much, it is not properly positioned. But most likely a combination of both.
At a minimum, add some air to the BC. In much of the video your bodies are at 45 degree angles and your kicking is what is holding you up. You want to be able to have your body more horizontal.
In the swim throughs, it seemed as if there was furious kicking to have you go horizontal and make it through without hitting the bottom. You should be able to leisurely glide through, body in horizontal trim and not even come close to hitting the bottom or silting it up either.
Keep working at it. It sounds like you and your father are wanting to improve, so take that all in that vein.
Still though, fun video.
BUT, this was only our 5th and 6th dive and more important than anything (in my opinion) is that my dad and I stayed in constant communication and stayed close to each other. We received many praises from out instructor after our certification dive about our good communication and proper signaling. Unfortunately I'm in the midwest so I am not able to practice as much as I'd like but we will be in the Keys in a couple months so I look forward to that. My 2015 goals are to obtain AOW, dive the ocean and improve trim/buoyancy.
