Pretty neat, although making specific crossbow classes didn't ever seem like most elegant way to give crossbows more option - fixing the weapon itself would be better start.

Anyway, class seems nice, I like the Sniping quite a bit.

I don't like quicker firing - no real synergy with sniping, and rather wonky image of completely unimaginably quickly reloaded crossbow - same with dual crossbow wielding.

The later is though obviously my personal preference, so that can not be an issue at all.
