Deej,
It works - it's not raw but it's not overcooked.
We often get into the downward spiral of diminishing returns.
It's hard to know when to stop but you stopped at the right time with this one.
Sibilant sounds aren't any sort of issue with this - & I'm the one who complains the most about that stuff.
The solo? well most rock songs have 'em and most don't do more than fill the space. This one works well enough - besides the vocal is the focus of this & the vocal is ACE!
If you're in a rut - do something out of the box, change the M.O., rather like this song...

Cheers
