The model for my service

I got booked by a company to provide my makeup service. They asked for my rate so I sent invoices. The next day they confirmed the booking and that they wanted to work with me. So now I feel that I should ask for a bigger price. I feel that I lost money. So I did a model. Can I have a review please:

C: A company booked me
T: I should have set a bigger price, I don’t know my worth
F: frustration, disappointment
A: Try to find a way to increase price to them
R: not excited to do the job

Intentional thought
C: a company booked me
T: I am thankful to be booked
F: excited and hopeful for my business success
A: planning for the services
R: I am looking forward for the big day
