Here's my attempt at it. My regular computer is in the shop getting fixed/upgraded for OOTP2006, so I'm reduced to using my laptop and it is
SLOW. Also the colours look different on this screen, so I don't know how close I came to your original.
Let me know if you want anything changed. I wasn't sure which size you needed it in, so I went with the standard 150x150.
I really like your logo - the only issue I saw was that the colour textures look different - almost as if they are transparent. Other than that, it's terrific!
