I think you're good enough, artistically, that there would be people who would be willing to buy from you. But it should be noted that when you start taking commissions, you also need to be emotionally and mentally ready to deal with some of the things that come with it - not just artistically.
Opening for commissions doesn't mean you'll immediately or always get business from it. Sometimes you do, sometimes you don't. You can't let yourself get down about it either way, and you have to work hard to make yourself be noticed. You can hope that it will maybe bring in a little spending money for you, but do not expect it to replace having a job right off the bat. There are people who make a living off art, but there are many more who don't, and it often takes a long time to get to that point.
It means dealing with a lot of different people with varying types of demands and attitudes. There will be people who are nice to work with, and people who are a pain to work with.
It means being able to treat your customers and your work with respect even if you are dealing with someone unpleasant. Sometimes that means grinning and thanking a person for their business even when they make things difficult for you.
Work should get finished in a timely manner, payments need to be handled maturely, and you have to be around if your commissioners ever need to contact you about something.
I don't know you very well, so I wouldn't know if you can or can't handle those kind of things, but that's the kind of stuff that you tend to deal with as a commission artist. If you are fine with that, then by all means, go for it.
