PS: the same construction of sentence in Russian "Looking ... I noticed" considers wrong as Bob Whiteman said. So I'd like to know, is it correct in English or should I say "When I was looking... I noticed"?
It's perfectly fine in English, it's just an informal way to speak. Everyone uses it. However, don't speak like that at a formal event, like a job interview, for example.
