/ic/ - Artwork/Critique

Let's be real: what kind of work do you need in your portfolio to get a job as an artist in the US? I'm not talking about commissions, not freelance, not your imaginary game company. Would it be:
1) Studies.
2) Naked women.
3) Landscapes.
4) Portraits.
5) Anime.

I mean, seriously, there are a lot of artists you admire, but if you had their work in your portfolio and it was actually yours, WOULD you be able to get a job in the US? Would an average employer look at your work and say "this is the man for the job"? I love anime, i love studies too, and naked women, but aren't i'm wasting my time if there is no demand for them in my country?
Please don't give me "oh, just does it cause you love it", then it's no different than masturbation or playing games, i.e. just wasting your time.
