I hope I’m not too late to give a reply.
I try to remind myself that even the popular artists struggle like anyone else and even they make mistakes. When it comes to making art, no one exactly knows how to draw/paint something correctly when they start and everyone’s artist journey is different.
If you keep on practicing (not just doing the same thing over and over, but analyzing your work critically)and persisting, you’ll get results.
As far as Commissions go, there isn’t a perfect formula on getting people to commission you. The only thing I can say is to be active in making/ updating with art, have an appealing/readable price sheet, and eventually people will take notice and will want to buy art from you.
