Is the sentence natural?

[Tan Elaine]

As Sammy was walking, he was looking at a car and heading towards a lamppost.

Is the sentence natural? Could it be improved?

Thanks.

There's nothing wrong with your sentence but one way it could be written is:

"As Sammy walked along he was looking at a car, and heading for a lamppost".
or "...., but heading for a lamppost".

There are a lot of other possible versions.
