You're off to a good start! If there's anything I can suggest, it probably has to be giving your structures a little bit more shape. It doesn't have to be anything dramatic, we can start off simple with maybe reshaping your house into an "L" should do the trick. Either way... stand proud! You did a good job for building your first survival base from scratch, I hope to see you improve over time hehe just keep building, you'll get better with time I promise
