I didn't know if you wanted text or anything. I've got all of it saved in layered format so I can rearrange any part of it or make any changes you'd like.
I kinda took the basic premise you gave me and ran with it, but I can make any changes you want.
Also, it's the same size as my sig (the boards just downsized it because I uploaded it as an attachment. If I upload it like I did mine (and I will when we're finished) it'll be the same size as mine.
I know you said subtle on the flags, but when you are working with the small size of a sig file, subtle isn't always possible so I went with blended.
