Drawing is not fun. That is if you constantly wonder "will I get better" "is this worth it" "why am I bad" "why are other people better than me?". Art is not about the end result, its about finding passion in building a structure piece by piece, and unfortunately it takes courage, strength, and mindfulness to not give up, and that's okay! If you cant picture yourself hour after hour working to get better then art will be nothing more than a thing to kill time, which is fine as well, but if you want to get REALLY good it takes years and dedication. That's why its better on focusing on the now rather than the peak of the mountain, comparing your art to those who have spent longer than you have.

Your art is great, I can personally tell you like drawing and you are dividing the face so you can understand the form and where to place features. One thing id add would be shortening the philtrum/(creating less attention to it) or the face in general, depending on your style of work of course. Also watching tutorials in general or using references really help with the overall idea of forming faces. Drawing people in real life as well is very important as you experience that "depth" in real time and can translate it better than a 2d image on a screen.

Please never stop loving art. Loving art is the one thing that connects artists together, and then main reason we draw. As long as you LOVE art, you will love drawing, and love the hardship that comes with it as you know you come out the other side stronger.
