Nice tune. The lead vox is a slightly too loud, I think. I would drop the panned doubled vocal and just have the vocal (or doubled vocal) right up the middle. After that you can decide if the harmonies are too low.

"ssss" sounds (and t's, d's, etc.): I fade out or cut any additional voices on the "s" endings (if it is needed). That way you reduce that effect and don't have to worry about the timing also.

Keep going, sounds good.
