Ancient Soldiers (Rough Sketch)

I know there are a few errors here but some are because the pencil I was using is not very sharp unfortunately. Anyway, I am planning to create a series of these drawings, starting here with the Ancient Assyrians, the first civilization to use helmets in combat. I didn't want to make it look bad incredibly realistic because that would take a really long time, so I took an approach similar to the style of the Civilization Revolution series style. I'll probably do the Romans or the Greeks next, probably the Romans because they were the more standard and more important in basically everything in the world today, especially warfare. But for now, this is a very rough sketch of some Assyrian Soldiers, armor reflective of the Bronze Age, or around 1500 B.C.
