Can i offer some advice?

Your screenshot says a lot.

The color is too bright, and I can hardly read the words.

Honestly if I saw that on a FB ad or anywhere, I would scroll right past it. I don't want to struggle to read.

Plus, you talk about yourself. People want to know what is in it for them. You don't mention the benefits of taking your course. Even your CTA button is about you.

You are a very good writer, so don't give up. I have no doubt you are intelligent.

If you are interested go read my post about Leonie Dawson. Maybe she can help.
