Hi Lucio. Using commas is generally for the effect of creating a natural pause or breathe, and to a native English speaker, the opportunities to use a comma are obvious. In creative writing (my speciality), it is possible to use a lot more commas to control the speed of the reader. For example, a text that is building anticipation or intensity may use a lot of commas to gradually build up to a point. In contrast, using fewer commas makes for faster reading, and so can be very effective for exhilarating or passionate text.
I hope this was of help.
