Definitely not hoppy enough for me, but that's just me. I would do at least a 1:1 grain:hop ratio. Also, I'd double (or triple) the dry-hopping.
Other things to note: I've been contemplating why my IIPA didn't dry out more. It was a pretty simple, and actually very similar grain bill to yours. It attenuated 84% but was left with too much sweetness in my opinion. I've narrowed it down to too high of a boil-off rate (1.5gal/h), causing increased melanoidin production. It was definitely darker than BTP's given SRM. Second, I just my tap water, which has a pretty even sulfate:chloride ratio. Next time I'm gonna bump up that sulfate to get the bitterness to really shine.
