Environment design - Ruined lake fort castle

The last environmental scene I will make in a while, since I will be starting to study 3D Character modelling. Featuring a ruined fort castle in the middle of a small lake.
Made in blender 3.1 with Cycles. No external plug-ins. All assets handmade.
I did it following the Blender course from Rob Tuytel (https://www.udemy.com/share/1013Ji3@-SpIui0vxmuTAH20zk7DmazALwg-HmF2NTwuDgxavwb2YwmgwAZBMHJ8o6yO2K9QuQ==/)
