I wouldn't really call manga a style. It's just the word for comics (and sometimes animation, surprisingly) in Japan, and can be any theme or style really. Although I'll admit that GENERALLY Japanese artists have a similar way of drawing, there's just no set 'manga' style they follow. Just look at something like Crayon Shin-chan.
My own style is definitely influenced by certain Japanese artists, just because I prefer a somewhat more accurately drawn body to the 'toon' look. But I still leave things quite cartoonish really.
