1) I don't follow tutorials, so what you see is up to my interpretation and my building style.
2) My preferred building scale is 1:1. I have been building in this scale for over 7 years now and I consider it my sweet spot. I probably won't build anything bigger than 1:1 scale (I'll leave the bigger scale builds to the other talented ship builders). I also understand it may not be a perfect scale to build in, but I try my best using scaling methods to accurately build my ships as close to 1:1 scale while also taking creative liberties to make the build work and be functional for the player.
3) I don't build cabins, engine rooms, or crew spaces. The reason is there is little to no information on what some of these spaces actually look like, so I'd rather not spend the time to build something that I don't have information on. There
is dead space on my builds because I primarily focus on class accommodations (Lounges, Dining Rooms, etc) and tend to focus less on passenger corridors, cabins, crew spaces, etc.
4) I highly recommend you use the Natural Texture Pack for exploring my ship builds. I exclusively build in this texture pack to give my builds a unique look and feel (plus its easier on the eyes for me). You can explore my builds without the texture pack but it wouldn't feel the same, so I highly recommend you use the Natural Texture Pack for full immersion. Here is the link for Java. 5) I am a strictly a solo builder. I do this because I like to have full control of my builds and also like to keep out the pesky griefers.
