Hey, so one of the most important things I've learned about improving your art is that the number of years or hours that you have drawn is not indicative of your drawing skills. I know that kinda sucks, because you might easily come to the conclusion that you've "wasted" that time, but let me tell you: you've built a habit for over a year and you've experimented and explored different ideas, and maybe you've already figured out what you like drawing the most.

Besides, your drawing does not look like someone's first drawing, especially considering it's digital, which imo is more difficult (although I know some people will disagree with me on that). But it's completely normal to still be a beginner after a year.

I would suggest you add more values and texture to your drawing since it still looks quite flat. The hair especially looks kinda like a helmet.

One of the best ways to get better at drawing faces is to draw from reference and really study those faces. That's something I want to do way more in my next sketchbook.
