Masterpiece. Good work. Although, let me give you some tips. 1.) Try not to use Sphere. And if you will, add to it. Shape it. Make it interesting, and make it fit in. 2.) Don't combine blocks that don't look good together. 3.) Design, Interior and Exterior. Your builds shouldn't be a simple small brick shack. Add to it. Shape it. Make it attractive, and interesting. 4.) Make it creative.
Very nice! I see you gained inspiration from flying around a majority of the plots in the creative world! :^)
Being agressive wont help you, I was just giving you some tips based on what I was told in my builder plot ¯\_(ツ)_/¯
My only suggestion is to try to use the /br smooth tool or to maybe use more complex designs to add detail. But that's a very good first build!
