I love how you've captured the charm and beauty of the architectural structures. Drawing architectural elements can be quite challenging, but you've done an amazing job with the ancient buildings, watchtowers, and fencing structures. And don't worry about the river running under the fortress wall; it adds a unique touch to the scene. The bridge you added is a brilliant idea and adds a sense of adventure to the painting.
