Whoa. That's quite an 'ask' and simple answers won't help you. Warning: Any time you ask for opinions, it can help to have a thick skin! We participate in a local multimedia group and when someone asks for a critique on a video they've just shown, we ask them where they want the dial set on feedback. To illustrate, a "1" means polite clapping and "Oh, that was lovely, dearie". A "10" means a detailed no-hold-barred mauling. The only rule is it must be constructive criticism. This is about a "7".
First, your gear is fine. You DO realize that first camera is a 'gateway drug', don't you? (Ask my wife about the gear closet!) Stick with that setup for now.
Second, big kudos for a narrative voice-over. Many beginners just lay a music track over the video and use on-screen titling to convey information. But more about sound below...
Watched your O1E1. First thought, you spent almost 5 minutes rambling on about off-roading/overlanding etc. while driving down an interstate. Then that long walk out to where the tent is. And then more, a lot more, driving down the interstate. You lost me at that point and I started skipping ahead. Think about this: The people who run TED Talks limit ALL their presenters to a maximum of 18 minutes (and most are much shorter than that) to talk about everything from tying your shoelace to the origins of the universe. Ask yourself, 'What is the story I'm trying to tell?' and then tell that story. I strongly recommend you start with much shorter videos. Anyone can make a 30-minute video. A good filmmaker can usually do the same video in less than 10. When you show your video to a test audience, do NOT watch the video with them. Watch THEM instead. What are they doing? Focusing on the video or looking at their watches? Or checking their email?
Video on the hard recovery point pretty typical of hardware install vids. Sound uneven. Stabilize the video or use a tripod more. Tighten the narrative.
Video on what to add to your rig -- points for the stand-up narrative. Stop looking around! Look at the camera! Good information! But tighten the narrative. On down the road, you could look at some improvement to your indoor space lighting.
So here is some food for thought...
"When people ask me if I went to film school I tell them, 'no, I went to films'." Quentin Tarantino
That's pretty much how we got started trying to make better videos, we looked for filmmakers whose style we really liked and tried to emulate their results, yet with our own personal style. (Favorites: Ron Fricke (Baraka, Samsara), Tom Lowe (TimeScapes), Phillip Bloom (numerous short films on Vimeo.com), and many more. We are still learning and probably always will be!
Then start finding some instructional videos on - yep - YouTube that provide good basic information in a style that you can actually learn from and apply to your own filmmaking. (DSLR Video Shooter, DSLRguide, etc.) There's a ton of them. Avoid the ones with blasting music and go for content. Other good sources can be found once you start looking around. For example, the PremiumBeat.com blog has numerous articles on many aspects of filmmaking.
"Sound is half of your movie." attributed to George Lucas
(Warning, Soapbox rant follows.) DO NOT NEGLECT SOUND. (Your in-car sound needs help.) Good sound can rescue a mediocre film, lousy sound can absolutely kill a great film. Learn how to do right along with everything else. (End Soapbox rant.) There are a ton of sources for free and royalty-free (learn the difference) music so that you won't have your video taken down by YouTube for a copyright violation. Start with Free Music Archive, Creative Commons, YouTube Studio, etc. for completely free music. The cost is only that it can take some time to find the "right" music to fit your video. If you want to save tsome time it means you'll spend some money. So, there's Premium Beat, Art List, and Epidemic Sound for a few.
Choose a decent non-linear editor that will let you grow into it's more advanced features instead of starting with a simple freebie that will come up short on features as your skills develop. No whining about learning curves accepted!! Personal recommendation is DaVinci Resolve. It is free and very powerful -- it has been used to do the editing on major Hollywood blockbusters. NO, it ain't easy... or is it? You can get started at the basic level in a few days of watching one of the many, many video tutorials available. A lot of them are produced by Blackmagic Design, the company that produces Resolve. (OK, fans of Adobe Premiere Pro/Premiere Elements, Windows Movie Maker, OpenShot, Shotcut, iMovie, etc. , my opinion, OK?! PS: I used PremierePro for 6 years and switched to Resolve a year ago and have not looked back.) If you want a YouTube resource for Resolve, try Jason Yadlovski.
Your filming is pretty good. Nice color, good and sharp. You need to tighten up the editing and work on sound.
You're embarking on quite a project and to get it fine-tuned is going to take some time. It will be worth it in the end.
