I have a couple of suggestions but I'm new myself so take it with a grain of salt. I feel like the pacing is a little slow. There are some parts where you're not saying anything and nothing is really happening (part where you're on the boat and going towards the island). I would get rid of 1:36-1:39, you cut in the middle of a sentence and I feel like you don't need the fading transitions. I would also get rid of the fast-forwarding where you're collecting materials since it doesn't bring much. I like the part where you're building the house though, that's super cool but I would put some background music. I would also get a better mic if I were you, your voice is a little muffled and I would also recommend trying to record your videos in 1080p or at least 720p. Once again, these are just recommendations but honestly you're doing great. I hope this helps!
