This is a simple model made in 1h 30mins to illustrate how to create distant background elements easily. The model only uses a single shot from Studio Ghibli's film Porco Rosso.
The technical quality of the model is quite bad, and it looks awful if viewed from different angles or from close up. However, the main point is that you dont need good topology or create every single model into perfection just for a simple background element. This looks pleasant from a distance, and it only took 1:30 hours to make, so there's that.
