You didn't ask for my opinion but I am going to give it anyway because I think you have potential.
First of all, stop using the word "Epic". It was cool for a short period 5 years ago or so, but it's been overused beyond cliche status. The word 'epic' has lost its meaning. Please don't use it unless something truly is Epic. Look it up if you have to.
Another word to drop is "guys". It's a poor way of addressing your audience that seems to be limited to Minecraft players. I could maybe understand if you had thousands of subscribers, but you've got one. Even with more, I would prefer to hear someone speaking to me. All you have to do is imagine you're addressing a single friend and drop the word "guys".
"Do you guys prefer this or that? Let me know what you guys think in the comments."
"Do you prefer this or that? Let me know what you think in the comments."
Sounds better, don't you think? It feels more personal and I'm not glancing over my shoulder wondering who the hell you're talking to.
You could stand to be smoother with your mouse movements and it's preferable to simply center your subject without shaking the pointer. Also, the fewer movements the better. For instance when you first entered your castle, I would have preferred you said "to the left goes up to here and to the right leads to there" instead of swinging the view at each doorway.
Check your audio equipment. I don't know how to describe it other than you sound like you're talking through a cup. Also try to avoid bringing your voice up at the end of sentences. It's not bad in your case, but I'm aware because I listen for it. You don't speak with a lot of ah's and um's and that's good.
Overall this is a lot better than most of the Minecraft Youtube videos. I prefer tours like yours over "hey watch me mine". If you do put your world up for download would you let me know? I'd like to see it.
