I wasn't listening in the studio, but even on my macbook speaker here's what I would suggest....
1) Be sure to have a good pop filter at least 1 1/2 or 2" off the mic grill.... and you should be AT LEAST a couple inches off that..... you don't have to be right on top of the mic.....
2) Try tipping the capsule down, or up, or side/side a little bit, rather than aiming straight at your mouth.... a bit more angle will help reduce the S's... sounds a bit sibilant
3) There sounds to be something that gets a bit honky in your voice - but not all the time, it's sorta only through certain parts. While distance, pop filter, and mic angle will help with some of this as well, it seems to be a tone somewhat inherent to your vocal... maybe around 400Hz? Many people have something around 250 and 500.... some just around the 360-400 range.... you could check both ways but I think you're in the 400 area, and maybe even something up around 800).... use a multiband compressor and bypass all but the band you want to target (this lets audio pass the other bands un-effected)... now set the target band (in your case likely 400) to reduce some gain as your vocal is hitting those parts harder. It's the same technique as DeEssing, but in different frequency range. I use Waves C4 or C6 for this... works GREAT....
^^A lot of people just go straight to an EQ for those things.... the problem with that, is that if it is something that is not consistent to the entire performance, then you are still being destructive to the entire performance. With this method, you are only knocking down that unpleasant frequency when it builds up and becomes an issue.... this will keep the vocal much fuller sounding... more natural... less processed sounding....
Anyway, good luck!
