I myself, with no help whatsoever....(actually I just copy and pasted a normal one onto paint and edited the colours) made this torso decal!
I did this because I got the DS game Lego Battles and noticed that the Brits had inverse coloured jackets and epaulets. So I made a torso decal to match.
Its cool that you took the time to change the colors, because from experience I know how hard it is.
EDIT: i invited you to my new group, so just go to it and join.
