Oh, can you just say 看我 as a whole sentence? I would have expected 看着我, but that might be because I don't listen to enough Mandarin... I feel like the Canto words for see/look would need either a suffix or more surrounding context to the sentence, like negation or something, or maybe reduplication of the verb (看看?), or at least a final particle. I don't know 看 as well, though, and anyway I could be wrong about the Cantonese usage, too...
