Siege On Dalaran

My new castle defend/attack map. Orc's attacing an human castle.
:foot:
Heres the little i have done to now.

Edit: Forgot to push "V" but anyway. Who cares.

Here is the fixed one

What should i do with these spots?

Take a look at the Dalaran (or similar) maps in the wc3 campaigns, especially RoC. I think that would give you some ideas about the style the inner city should be in. How the exact layout should be depends on what kind of map you want to make, I guess.
