I agree with Ishmaru that the column is just lacking.
I couldn't help noticing that the temple in the MG engine and the snapshot of of the temple look different. The temple in the MG engine has 1 texture which looks boring (a bit like the roman temple xD).
The temple and well could be used with a little bit of work. The other textures on the temple need re-applying and I would shrink the temple, and add something interesting in the centre of the temple.
I'm not sure how I'd edit the well, but I'd try to make it look vaguely like some sort of creepy portal well
I love the units you chose! They look fun :-)
Hope to see this mod out soon!
