Its tricky doing buildings when the main wall pieces are the window bricks.
Advice on buildings:
Most players, new and old... tend to make the outside frame of a house/castle/building/whatever first.
Then they move onto the insides, only to find its harder and displeasing to the eye. trying to get in those floors and stairs, and any stuff less then repetitive, floor after floor.
This also causes the build to appear smaller and cramped compared to what the builder originally planned. Since as a blocko avatar, we have the advantage of being to scale, rather then real life lego sets would have us believe.
But I like what you got going. As you wprk on this just remember to try and mix things up. So floor after floor people won't be seeing the same thing.
And that spire antenna with the flashing red light that all tall buildings have so to keep helos from crashing :p
