Show don't tell

Before

The shadow was tall and scary.

After

The stairs creaked; it was getting louder and louder as time passed. I saw a glimpse of its tail; it was munted up and old.

The shadow towered over me like the sky tower, my heart was thudding in fear. It was so close I could hear its breathing. ¨Meow¨ oh it was just my cat bob!
