It's true if you're just straight up copying a photo, you're going to have to compete with the Chinese commercial art industry. But they don't do creative work, so any amount of deviation from just copying a photo and you'll have a leg up.
Frankly artists here don't want to copy photos, and even the studio artists we interviewed in China don't want to do that either. But it's a steady source of income for them.
I'd suggest you talk to some artists here first and get their opinion, and then talk to some of the artists in China, because that's what I did.
