Did you change the panning of the clarinet at some point? It's mixed so low I can hardly tell...
Since you're just starting, I'll share my main complaint about recording clarinet players. Just about every one I've recorded has been unable to keep air from escaping from the sides of the lips. And then they ask me "what's that hissing sound on the recording?"
I reply: "It's you. Your lips are hissing at the sides with escaping air. Can you try to avoid that?"
"But I was taught that that was ok."
"It might be ok in an ensemble or live, but it sounds like hissing on a recording" (personally, I don't think it's ok live...)
"Can't you get rid of it with the computer"
"How much money do you have" / "it's better if you get rid of it with your mouth" / "nope."
And so on. One of the only clarinet players I've encountered who don't hiss happens to also be a recording engineer so he knows how horrid it sounds when recorded. And he absolutely hates all the other clarinetists who hiss.
So here's a tip: Learn not to hiss when you play.
(not that you do. I didn't notice any hissing.)
Good on you for learning a new instrument!
