Assuming your commissions are larger in size/canvas, your pricing is pretty fair for the quality of your work.
Some advice: I have had plenty of people call my prices "steep" or "expensive." Yet I still get commissions. Genuine customers who value your work will pay for it whatever the price is, because they understand that art is a luxury. They also know that they're buying a custom product created by you from scratch, and custom products take more time and a considerable amount of skill. Other factors such as a pleasant personality and good turnaround/good business transaction increase the chances of repeat customers who won't mind your prices and want to support you in any way they can.
This is entirely optional, but I've been told this by some artist friends: If you feel like you've improved over the year and see a quality increase in your work, consider raising your prices at the beginning of the next year. If you're not comfortable, keep them the same, but you can bump them up later if you think you're putting in more work than what you're being paid for.
Good luck! ❤️
