I've learned I don't have to bash my head against perspective and just make up things to compliment a room or landscape as I go; it's perfectly fine to draw a guide of where to place furniture/buildings and THEN plan out perspective with some digital tricks.
This is the guide that made me realize this after I spent the best part of last night just sketching furniture in a 2-way perspective room trying to discover where it looked best. Thankfully it was just the sketch.
