A case of Freelancing and Tax

I am a freelancer working online in software development. I exclusively work with overseas clients(exports). For 20-21 fiscal, I crossed revenue of 20 lakhs. For that year, I claimed 50% expenses under section 44ADA for professionals. From 21-22 fiscal, the income is higher and I plan to use section 44AD to claim taxable as 6% (as all transactions are cashless).

As I've crossed 20 lakhs, I am going to register a new company as proprietorship. I also will be paying 0% GST due to exports being outside its purview.

Does it all seem to be in order or am I making any mistakes?
