If you manually edit the sibilant sounds using a preFX volume envelope, (or the Clip Gain feature), you'll get a better result. You can also look at using the saturation by sending the audio to a saturation track and EQing that saturation track to reduce the sibilant emphasis. In the end I think the saturation may be what's causing the strident/unpleasant edge to your voice which means TOO MUCH saturation added to the track.
The drums aren't over complicated, rather, they seem to be added to instead of being integrated into and that propelling the song.
