This looks great Ilanthar!

About the linework that was mentioned I personally think it's fine like this. The sketchy lines adds a lot of charm to this, that makes it more unique. However, I think the map is to "empty" and lack in details. Some chimneys, cannons on the walls, flags and people – and different stuff like that, would add so much "life to this map". Then it would go from great to awesome in my eyes. (I comment on this because I feel that the map could be so amazing with little more work, while it at the moment don't really reach that "I want to explore this castle" feeling – if you know what I mean).

Keep up the great work!
