Yeah. Uh. If you're going to bend those notes, then at least make them on pitch. You're ending on a note that isn't in scale, and it sounds awkward. Personally, I'd ditch the whole note bend thing, but, whatever.
Setting a proper pre-delay on the reverb, along with minimal EQ and slight compression, should be all that's really needed. Other techniques can be cool and can add something extra, but those are the big 3 for vocals. If something isn't sounding right with the vocal, as far its place in the mix, then start there. Pre-delay times are usually in the 70-100 ms range, but there are ppl who use times outside that area.
I think the issue is more the vocal performance than the processing, for whatever that's worth. I'd edit out the excessive lip smacks and hesitations. They don't add anything but a sense of amateurism.
