I mentioned earlier today that my great neice, Leslie, sent me a drawing she had done. It's of David Bowie as "Jareth" the goblin king from the movie Labyrinth. I've not seen the movie, but I know this looks like David Bowie.
Leslie's mom was always very artistic. Leslie has never had any art training and I'm not sure if Kathy had any either. I do think artistic talent is partially genetic.
However, I do believe anyone can learn to draw, too. It takes lots of practice. But, I know my own "skills" (I say that generously) have greatly improved since I started making an effort to draw regularly. Part of it is that you just have to get past the worrying about it being bad.
I am not nearly as talented as Leslie. I rarely attempt to reproduce an actual likeness of a human being. I prefer to stick with inanimate objects that remain stationery for long periods of time and who's feelings are not hurt when my drawing does not look like them.
