do you plan on hopping it any more? I don't have a lot of experince with brewing from cans so I don't know how much bitterness it will add, but you may want to think about adding some more hops, especially with about 8 lbs of extract for a 5 gal batch.
Beer, happy Produce of our Isle/Can sinewy Strength impart,
And wearied with Fatigue and Toil/Can cheer each manly Heart.
Labour and Art upheld by Thee/Successfully advance,
We quaff Thy balmy Juice with Glee/And Water leave to France.
Genius of Health, thy grateful Taste/Rivals the Cup of Jove,
And warms each English generous Breast/With Liberty and Love!
(Rev James Townley, 1751)
