Tips and advice oil pastel

I decided to try new things this year, and one of those is oil pastels. I ordered a mid tier quality set, pentel, and it should arrive in a few days.

I know I can use white spirits to make them a little more fluid, and I plain to use them on heavy oil colour paper. I have a small bottle of that.

I just wanted to ask if anybody had any tips or advice or just info to share, what you think would be useful to know for someone who hasn’t used oil pastel in over 30 year. Even fun facts or to point me to artists I can look up who use them.

Thanks ever so much in advance!
