Hmmm....Perhaps you should narrow the white and black lines slightly and put a narrow green (astroturf?) line in the midst of the brown. In my opinion it would liven it up a tad.

Bear in mind that I'm not, nor will ever be a football fan! But the tartan would be snazzy!

As for "over the top," while it may not be my cup o' tea, its about what you like.
