I'm talking about obvious pitch shifting effects on the vocals, not subtle tuning, or the delay and ambiance. The lead vocal in the first verse sounds fine, apart from the very last word where you obviously added pitch shifting for effect. The background lead and backing vocal in your choruses sounded fine. I didn't didn't hear any obvious pitch shifting, just delay and reverb. Great chorus, BTW. It's not easy to make a chorus work by dropping the energy level, but you do it here and it works.
Where the vocal effects really become problematic is in your second verse. The lead vocal sounds deliberately mangled, to no advantage. It's all over that vocal, but especially at the end of the lines: "wrong," "long," etc. I'd just so much rather hear your vocal without that stuff.
But hey--just my subjective opinion. Millions or billions of listeners around the world must appreciate that robotic pitch shifting, as it has been the fad in pop music for a few years now. Maybe they're right and I'm wrong.
As for the crash, look for example at that left-right-left crash sequence you have around 1:01. They are too soft to be adding much excitement or punctuation, which is the traditional function of a crash. And yet they don't blend into the mix the way a ride or an open hat hit might. They just strike me as odd.
Hope this helps.
