Just keep at it.
I've been drawing since I was a young kid in Nigeria. I recall very well drawing on the ground in our yard with my brothers.
I only started putting my work online around 2005. At the time, I was nervous since I was following the shadows of many great artists I found on Pixiv.
I was especially weak with character design. Something about the human anatomy always eluded me.
I did, however, get better because I just kept practicing, I enjoyed it and I just watched more anime for inspiration.
Gradually, I also got better at illustrating cars as well. The picture above was drawn on paper, and then I added a glare effect using Photoshop. One of my first forays into Photoshop and Adobe Illustrator.
Another thing I also enjoyed drawing was military jets. My brothers and I made a hobby of knowing all the military aircraft used in any major war. An odd hobby I know.
Overtime, I also got better at drawing them, and I started coming up with my own unique concepts. A lot of my inspiration came from shows like YukiKaze, and the Macross series.
I could go on showing more of my artwork. But I think you get the point am trying to make. A lot of people have asked me in the past how I got to this level of skill. But I write this to show that it took a while.
In anything, be it art, programming, martial arts, or comedy, when it comes to honing your craft, most of us will benefit greatly from consistent practice. It also helps significantly to enjoy the process of getting better. The journey is also a reward in itself.
