As I was approaching from the northwest to an airport with parallel runways; intending to land on the eastern of the two runways.  The Tower closed early because of COVID-19; and traffic was using Runways XXL and XXR.  I elected to fly a left downwind to land on Runway XXR; partially because there was traffic to the east of the field that was planning to fly a right downwind to XXR; and I did not have visual contact it.  I landed uneventfully; but in hindsight; it would have been better to follow the proper pattern by overflying the field; and descending to join the right downwind for XXR.
GA pilot reported flying the incorrect pattern after the Tower closed.
