Here are some sketches on those topics.

Equipment of an Infantryman

Granted its not really accurate - The Pilum isn't really in use by the 4th to 5th century just before Roman withdrawal from Western Europe. The course of warfare has evolved by then with the Romans so effective and technologically superior - it makes no sense to train and equip expensive troops when the frontline brawlers could win the day.
On to the Normans - I was intrigued by the written description of their hairstyle. I've given it a modern spin here - when I first heard the description I thought they must've looked a lot like modern infantrymen with crew cuts.

There's a lot more freedom when it comes to accuracy of the uniform in this 1500 year stretch. Most soldiers paid for their own equipment and each piece is customized to some extent. Gives room for creative freedom :D
Pretty cool exercise - I need more practice. The Holbien Waterbrush is great if you're working on a more intuitive level as it always stays wet as long as you have water in the well - but sometimes for detail work, I have to switch back to a normal brush for dry brushing. Still, its quite an interesting piece of equipment.
