I'm not all that familiar with the beer itself, but 2.5lbs of crystal/caramel seems a bit high to me. I'd drop the second "caramel malt" entirely and reduce the amount of 75L to ~.5lbs. There'll be a lot of crystal in the extracts, so as-is, your recipe will come out pretty malty.
I'd also bump the Chinook and 30 minute Centennial to later in the boil (say, 15 and 10 minutes, respectively). But again, I don't know what c-note itself tastes like, so your mileage may vary.
