When I listen to this, a castle in a forest is exactly what I picture! Rightfully titled! Haha.
I also think about the Meridell castle in Neopets: The Darkest Faerie, but that's just me.
Anyways, this song is very calming and majestic. I wouldn't change anything about it, it's perfect. Very professional work was done here and I'm amazed. This is one of the best songs I've ever heard on Newgrounds.
