Skivvies' Castle

Attempted drawing Skivvies' castle in Novelette. 

Now some information about this image! 
I was half studying, half drawing whilst creating it.
I drew it based on what I thought the opening of Rain's story looked like.
This is the first time I have drawn a castle.
I still need to work on perspective drawings, but doing something like this has allowed me to practice.
The castle looks WAY too small if the trees in the background are normal sized.. otherwise they're gigantic. 

Overall I think I did a good job considering this was my first attempt at something like this :]
