not bad for playing only a year…so you read up on badminton (from joint date) for at least 5/6 yrs before actually getting on a court to play? thats unusual. look at your opponent, for the most part, he didnt need to go back beyond the double service line to return your clears and you were constantly force to play weak defensive clear.
for now, get your clears to the back, which buys you more time to return to base and harder for opponent to attack. make more effort to get behind the shuttle at the back, stop doing passive slow loopy drops. once you do that, then improve your front game.
