Mike, the only way to learn is to experiment
This is a good experiment
IMHO I think the classical sections are fine but I didn't like the rock part. I thought it came in abruptly and didn't blend well with the classical section. Also I would EQ some of the highs on the lead violins. But this is just my opinion.
I do give you a lot of credit for trying this experiment and I hope you had fun.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
