Thanks for sharing your video! I really gotta get over to Anza Borrego one of these days soon!
I'm no expert by any means (we're also just getting started on YouTube), but I do have a couple more pieces of constructive feedback for you:
Audio:
Consider picking up an external microphone and a "dead cat". A shotgun mic will focus the audio gain and the dead cat will knock out most of that harsh wind noise. The directionality of a shotgun mic will take some getting used to, since it will primarily pick up from whatever it is pointing at - so you won't really be able to talk from "behind the camera" and pick it up well. For those kinds of situations, you may also consider picking up an inexpensive lavalier mic.
For our videos we use:
Rode VideoMic Me ($60) for our phones
Rode VideoMicro ($60) fits a shotshoe mount on a camera
A random cheapo Lavalier Mic from amazon ($~10)
Both of those Rode mics come with a "dead cat"
Video "selfie" shots:
* It looks like some of those selfie shots had the DSLR lens at somewhere around 50mm or more (i'm assuming you had your arm almost fully extended). If you are able to, pull the lens back to somewhere like 24-35mm, that should also help with the camera shake a bit more. If you are limited by lens or in a pinch, just prop the camera up somewhere like on a rock, table, vehicle, and then take a step back and start talking.
* When filming with your phones, make sure to hold/mount it horizontal!
Nice job, keep it up!
P.S. The bees at 12:28 are going to give me nightmares for a week.
