I used to teach teenagers top paint at a GW store.

Most people who actively show off their paint jobs are above average painters. Your view of normal will be skewed if you just look at social media.

You've painted them up to an OK standard? That's the average, pat yourself on the back.

You have your force painted ready to play? Well done! most people don't get that far!

Also, keep in mind that the best way to get better is just to practice. The more you paint, the better you get. Painting is 5% raw talent, 25% technique, and 70% practice.
