Many thanks for the comments, everyone!

I like what you have done with the themed bases. How about a picture of all three together so we can get an idea of how a massive army will look?
Sure, if it ever grows to full army-size.

By now and according to the list I'm using there are still 4 bases to be added. Unfortunately, these are all big units in dense formation, so I have to purchase (and paint, of course!) quite a few models beforehand. Therefore, please don't hold your breath for an 'army shot' to appear.
