This is a very good example of your style. But you should find a way to draw art with less thick lines. As you seem to not be Ble to see much detail because of it. Like th ed fingers. Maybe try shading too.draw on paper then scan it with a scanner? Some printers can also scan as well. Just find out a way to use less thick lines. It works in some areas. But use a mix of colors, and thicknesses.
Plus I can see tiny ish circles. Which seem out of place.
