Gothic fantasy castle UE5 (Stormfang Castle)

This piece is a semi-realistic/fantasy environment that aims to transport audiences to a smoky medieval castle. All the assets, including my attempt at foliage, were made by me. My main influences for this piece are the excellent manga series Berserk, the TV series Castlevania, and, of course, the Souls games.

Story
The story revolves around a vampiric lord who still lives in his small, isolated keep. The castle is located in a rocky and remote area of a mystical kingdom. All of his servants are people he has stolen and bewitched, taken from nearby villages and forced to serve him. If a servant is loyal, they are buried respectfully. However, in the nearby town of Pabiton, the townsfolk are fed up and want to put a stop to their people disappearing. They decide to lay siege to the castle, attacking it with whatever arms they can find. The loyal servants put up a makeshift defence, but the tide starts to turn in favour of the attacking militia. This all changes when the Count appears from the mist...
