Designer, 5YOE, 12LPA, Remote. Should I ask for more?

I have 5YoE in the current company, and about 7 years overall. I bring specific domain knowledge to the team, as I have a PhD in Science. The regular increment is 10% even with performance exceeding expectations.

I am considering branching off and starting my own business. Last year I made around 6 lakhs by freelancing. That too without any active marketing and advertising.

What should be the best course of action?.
