Pet peeve but it all depends on your goal. Saison is such a nondescript style that "anything goes", to a certain extent.
You want a classical saison or a hoppy farmhouse ale? I'm guessing the latter, in which case your recipe looks good (although I'm not sure about the BelleSaison but that's just me not liking it much in hoppy beers so far).
Gravity goals?
IBU?
ABV?
Without any of these, I'm probably not looking at "your" beer, but rather at what I would brew with those percentages. A 5% classical saison is a hell of a lot different from an 8% farmhouse ale, is what I'm saying.
I'm not too sure about the aromatic, which I can see clashing with the BS and the hops, muddling things up if dosed too high, but then again, it may well be just the thing that brings it all together. Like I say: I'm not sure about that.
Biscuit...I'm not sure you want biscuit in your saison, but (repeating myself somewhat and apologising profusely for it) it all depends on what you, the brewer, want.
