Zweitholou,
Yes, it looks much better, thx for understanding.
Now, when it looks close to perfect I almost feel bad pointing out little detail :]
I have been wondering, on 3D design and what will happen when you walk by the main road... The more faces you see at once, the lower the FPS.
If the road was to be straight, you will see all the buildings from one gate to another, that's not good. So i propose to curve the road.
Thats the only reason for it to be curved and quite a good one!
You probably don't feel like redrawing it, so i can just warp it like i was doing before if you allow me.
As for textures, they are part of 3d mesh. You can't make mesh without textures and texturs without a mesh if you want both to look good in conjuction.
The phase is called 2d... but i really see no reason to not make screens of meshes, which may come into phase 3d unchanged.
I have already did that with corridor. Yes, you should answer "No" when i asked "can you believe it?" ;P
the same way as 3d artists have something to do in this phase, you will be same as needed in 3d phase as you are now :)
Spikes 
are nice, but i would forget about them.
The minimum faces needed for a single spike is 3 + it won't look too well. How many spikes do you except on a 1m
3? From your image - a lot. The effect will be very similiar like wth the grass foliage (I'd rather save the faces to make the city walls interior better)
You can use two sided planes for spikes too... but for satisfying effect you still need lots of faces over the walls.
Klyros or any other race would not attack any race city on a large scale. That does not mean flying beasts would not. ;)
I'm with UtM on that one.
Maybe they fought in the past, but it is long long over. Now Yliakum has one geverment and one military, which answers before that goverment. Yliakum people don't fight themselves since very long, if they ever fought to a degree that they attacked fully fortified city.
I think pterosaurs and megaras are definetly used in battle, to bombard enemy and being out of its reach at the same time.
Great tower!
Damn! I think they would build the bottom as wide as the first balcony and of stone. I think they would use stone from their fine quarries, rather than buy so much metal from somewhere else. That would be really a lot of iron, if count all towers, maybe even more than the Laanx temple itself!
