As an artist I think there are 3 important things:
1. Learn: You gotta learn things in drawing like the anatomy and how you make the sketches. Also learn how to do things like coloring and adding shadows. And learning which are the best programs for drawing.
2. Practice: At first your drawings will not look good. It happens with all the artists. When Joseco drew a pony for the first time the proportions were not so good in the legs.

And now he's one of the best artists in the community.
3. Want it to look good. This one is the most important in my opinion. If I drew a pony without effort it would just be 2 ugly ovals with a neck and 4 sticks. You need to know it's not so easy to make it very good. If you know there's an error or something that doesn't look right you don't say ''oh fuck that, no one will notice it''. No! you gotta fix that error so you can make it perfect.

Also, remember there is not such thing as bad art, but you have to know there are drawings and artists better than others. Your art is good, but you can make it better.

TL;DR:Learn, practice and put effort so you can make your art better.
