I think your art is good enough for commissions! I think what you want to think about is how much time does it take you to make a piece. Then you should calculate a livable and fair wage based off of your skill set. Don't charge less than minimum wage!
The things is with art commissions, it's better to do less than more. Sure you might make the same amount of money charging 5 dollars to 6 people and create 6 pieces of art for 30 bucks, but it's better to draw one picture for 30.
I'll leave some of my commission info here as an example (just prices).
For example the "Animal Crossing Style" if I work on it non-stop and once I get feedback from the client probably takes me about 2 hrs to make. So I'm making 20 bucks an hour. I'm also setting a limit on it being only for one character, charging extra for other characters and for a complex bg that isn't just a colour field/gradient or small doodle.
These are also a baseline. If I had a client who wanted a ton of revisions (more than 3) I would charge extra for that. If the character is extremely complicated and I know would take me forever, I will charge extra.
I live in Canada, so RIP expensive shipping - but I've also calculated for that as well! Even if actual postage only ends up costing a buck. I'm charging for my time to get it printed, my time to package it and pay for packing materials and my time to go to the post office.
The other thing to is don't get discouraged if people don't hop on the commission train right away. With COVID people are being more stingy than usual because jobs are up in the air. As well, if you don't have a huge social media following it can be hard at first to gain clients. The main thing is to not give up! Keep creating work and working on your own art! People will take notice. Also, tell your friends and family as well that you are opening commissions. You will be surprised how many people who are maybe not the most internet savvy also want art!!
Do not give friend discounts. You are offering a valuable skill and true friends will recognize this and pay you what you're worth! If a friend or anyone really wants a commission but can't afford it, meet with them in the middle with something. Maybe they can't afford a full colour commission, but you can offer a black and white one instead for cheaper.
I hope this helps out!
