My experience as a pro artist is that it takes about five years of directed practice to go from “I like to draw” to “I draw well enough to make a living at it”, followed by another 5-10y to get to “I just sort of move my hand and Art happens without much thought because I have internalized a ton of stuff that I used to have to do on paper”. YMMV.
