First things first: The Toms are _exactly_ my thing smile

I wouldn't have let them play through the complete song, a drop would give the listener a moment to breath and reflect and give them even more impact when they come back in.
But they really are a great choice for giving the song its drive, and they work perfectly with the guitars and those sexy little fills.
Despite all those guitars, the mix sounds really open and clean, leaving plenty of room for your (beautiful) vocals.

I think your arrangement experiment is a winner [Linked Image - Only viewable when logged in]
