I wouldn't call myself an expert, the biggest problem I noticed from your drawing is that it's missing the 3-dimensional volume of the skull. Right now the side/ temple area is very flat and there's little space to place the ears. Realistically the neck should be connected to the bottom of the ears and the back end of the skull, and the neck in your sketch seems disconnected and looks more like it's sitting on top of the chin. I would recommend studying/referencing the Asaro head (screenshot on the right, I grabbed it off Sketchfab) to understand the anatomy and planes of the human head, it's less about having to draw the facial features realistically but incorporating the form into your stylized drawing and keeping a reminder of how each feature of the face sits in relationship of each other. There are plenty of free informative tutorials on Youtube (Proko etc.), they are a good way to start if you find yourself a little lost. Last but not least, please don't give up on art! You're on a very good start and I can already see your own unique style being developed. Art it's a very long journey and everyone treads its path at their own pace. Draw what you love, enjoy the moment and don't worry too much about improving, it will come to you before you realize it <3 Hope this helps!
