I'm no DIPA expert, but based on your goals, I don't associate these hops with piney. Chinook can be slightly rough but you're using it early enough that it should just bitter the wort.
Strictly my opinion, but 25% of crystal and carapils, when combined with a mash of 154F, may leave you with a bigger/fuller mouthfeel than most DIPAs. It's tough to get a true DIPA to dry out and feel fully attenuated. If you want drier, I'd recommend either mashing lower or reducing the amount of those grains.
That said, at 1.063 and 70 IBU (Tinseth) this is slightly low for a BJCP DIPA if you go by those guidelines at all. But it seems like a malty hop-bomb, which would be pretty nice. Brew what you want/like and adjust the next one to suit your tastes.
