Looking for layout ideas and feedback

Update in the comments! After moving recently I will be able to build a permanent layout. Very excited to start. The space is about 3,50x4,60m (roughly 11.5 by 15.1 feet) and I'm able to use about half of the space for a layout, in any shape or form. What track pieces am I looking to use: - R56 & R72 (bigger if we the space allows with some bonkers ideas) - For switches minimal R72, anything R72 and up looks fantastic Important things: - Space for a 3-4 track train station - Some elevation...
