Towers... back to the Emperor

It's been a while since my last post... I've been away for work for the past two weeks so got very little hobby done.
I did take some foam-core with me to see what I could come up with for the towers on the castle section of the emperor.. I came up with this but it's still a work in progress

I'm going for a look that is quite similar to the epic scale emperor... so I have 3 more of these to make and then a bunch of details to tie everything together..
