A little practice with references from DK Eyewitness: Knight. I love those books!
Photoshop is driving me mad, though. I tried everything, and this still looks brownish even though it should be grayscale. Maybe it's just with Blogger/Google that it gets messed up; the last few posts here all look brown - and the very same files look just fine on DeviantArt (as well as in Windows and Photoshop). I hope it's Blogger's fault, cause I'm out of ideas as to how to fix it.
