Wow, nice submission sakura! Great job on the two characters as well as the colors and shading. ^_^
2 things:
1. It is a little odd to see the background pattern through England's shirt. Makes him seem like a ghost or
something...
2. I don't think you necessarily need all those "stamps" in the foreground... they kind of detract from
the main focus of your piece (the two guys).
But overall, good job! I can't wait to see more of your work! ^_^
