When you start a sentence sequence, for example with "he", would It be correct if I construct the sentences as following:

    He started walking down the road. Took a sigh. Was amazed with the beauty of the sky.

I know that I could construct the sentences like below, if I am not wrong:

    He started walking down the road, took a sigh, was amazed with the beauty of the sky.

But I don't want to use lots of commas. In my opinion even if the way I build the sentence is wrong, people wouldn't find It absurd, am I right?

Please don't give me alternatives of the sentences. I just want to know about the exact example I gave.
