Feedback for Leftover-Grain Imperial Nut Brown Ale?

[drubes14]

Hey all - trying to get rid of some leftover grain by making an imperial nut brown ale. Wanted to some feedback on the recipe itself... is the grain bill too complex and busy? I'm hoping for a nutty, toffee, biscuity profile. Walking a tight line between getting rid of leftover grain and overwhelming the grain bill!
