everyone has its own talent if you want to be good at something you should keep practicing for you to be able to be good at it. I do a lot of sketches and digital painting everyday even after work when i got home. the key is dont stop learning new things and move your way up. U should also consider to accept mistakes and avoid doing it twice. be open to critiques it will help you grow more in your skills. Goodluck to you my friend. draw everyday!
