Help with a few sentences??

Do these sound like run-on sentences? If so, how could I fix them?

Thank you!

All in all, my experiences with classical music has allowed me to appreciate that within the rigor of the fine details in technicalities, there is freedom of personal touch that allows artistic expression, which is only possible through a strong foundation of the technical skills. To complete the analogy, a strong education is necessary to channel the best ideas in a meaningful way.

If you are going to use the plural (experiences) then you need to use the word - have, not has (my experiences with classical music have…). Or, you can use the singular then you can use the word has. - (my experience with classical music has allowed…).
Sentence number one is a bit long. I would suggest breaking it into two sentences. I would suggest ending after the word expression.
All in all…expression. This is only possible through…skills.
