I only made it to 5 minutes

, but I think you're being to hard on yourself. Shifting looked smooth. And while you claim to not have been looking through the corners I can think of several instances where you most definately were. If it makes you feel any better, we all fall into that trap sometimes, and just forget to look through.
I think you should be really proud, you're making amazing progress.
If I had any tips? I'd say be a
little more agressive on the brakes. It'll let you get your feet down a little sooner, and help your balance a bit while stopping.
That and your camera man should be sprinting around to make sure those trees don't get in the way
You're doing great, don't stop. Not for anything.
Of course I'm generalizing from a single example here, but everyone does that. At least I do.
