1.) A Knight with a Raven on His Right Shoulder. Should look about 6' 2-4"ish and blonde hair. (Unless you dress him in a helmet that hides his face.)
2.) A Persian Army General, with an updated look. He should be dressed in some fashion of armor and he should be as equally kick ass looking at the knight. He also would be the same height and have light features.
If you're feeling especially creative it would be ideal to have these two characters walking away from the far off silhouette of a broken and burning old roman city... they would look like they escaped alive... not like they destroyed it.
These two guys are going into an art project as part of a present for a friend, so there is a small budget. I can pay $75 to the artist who can create them.
