The Tower

This started out as a speed painting. I had never done one and felt rather good about the end result. So I went back into it and fleshed out the details to give me what you see here. It's a little different from my usual post but I need to do environments.
I don't think I can call this a speed painting any more. I spend a good part of the day doing this.
Please let me know what you think.

(edit: made an attempt to blend the castle more into the image.)
