Castle- Descriptive Writing

As a part of our Narrative unit we are trying to improve our descriptive writing. Our goal is to improve our descriptive language to help the reader understand the setting.

I was traveling through the forest when the car ran out of petrol. We had to camp for the night.

Then suddenly I saw a spooky castle. I went up closer. There was a swamp that had sharks and man eating crocodiles. At the front of the castle a big  draw bridge with two big chains.The castle's door was big and heavy with a big rusty handle.
