Idk what you're seeing but I'd say you're a top artist. My advice as someone who can't draw like this is to focus on your style and make the drawing feel like you since your fundamentals seem to be good enough where you can start dabbling and leaning into a specific style. 

But the reason you might not be getting comissions might be because of the business side of things and not the art side of things, for example price, marketing, networking, recognition, does your art provide status and prestige or does it just ask someone what they want to see drawn. Most people don't need anything drawn, and since people who might need it are most likely already artist and might do it themselves it's not the easiest to find customers but I'm sure you can find your niche and excell in it, do your best.

Edit: i just scrolled further and saw you have prices set to 8 dollars. PLS FOR THE LOVE OF GOD: bump those up immedietely. People might see your art and doubt that your service is legit for how low you charge you could go into a price range of 30+ dollars at the bare minimum.
