Battle of Belleauwood

"I had just read Ernst Jünger's brutal World War I memoirs, 'Storm of
Steel', and was really inspired to do some imagery from that time
period. Naturally, I went looking for the Marine Corps' side of the
story and read up more on the Battle of Belleau Wood. Initially I
thought about doing this with traditional paints, but there's already
a lot of incredible paintings depicting Belleau Wood. So I did a
sketch in ink brush, which I then scanned and colored in Adobe
Photoshop. Although I do love doing drawings from real life, with this
image I deliberately took a more exaggeratedly stylized approach to
make something that looked like it could be a screencap from an
animated film about Belleau Wood."

I'm really digging some of the art work that these guys are putting out.  Who knew but they even have a combat art school.  Cool.
