I can tell you put a lot of thought, effort, and detail into this scene and it came out very well! Good job! Maybe a ship scene like what Lego did with the trench run and mini scaled ships and structures would be a cool idea that would really challenge you. (Maybe a Rogue One scene of like the battle of Scarrif or Jedha? :])
I don’t have a part list for this, but I really recommend to just start building. Almost all of the best details in this were made up on the fly with whatever pieces I had close by 👍
