G.I. Joe Comic Line Art

Here is a G.I. Joe Line art I did for a Project in my advanced Photoshop class.  Please let me know what you think of it.  (No copyright infringements were intended.  All photos were downloaded by the instructor of the class.)  I would like to dedicate this one to our U.S. Military; the REAL American Heroes.  The blac and white in your left is what the instructor gave us.  All the colors in the finished one, on the right, were taken from real military colors and the shells for the ammo are pictures of actual ammo being used by Our Military.  The flags used are real U.S. Battle flags.
