Camillo! This is awesome man :) Very clear and articulate with the drawings which is great! Especially the layout view showcasing the entire area is useful. The only thing I'm going to point out for now; however, is in your second page of drawings when you're depicting the drawbridge. The chains holding up the bridge itself seem a little too thin and thus a little too weak to pull and lower an enormous bridge such as the one you've designed. I'd suggest possibly making it slightly larger or even include multiple chains to help relieve the tension from just the two chains itself. Other than that, great work man!
