Grant McCann’s side had taken the lead in the first half through Bowen’s sixth goal of the season, only for Ryan Manning to draw the visitors level a minute before the break.
Eberechi Eze won and converted two second half penalties to give QPR a 3-1 lead and although Josh Magennis’ stoppage-time strike gave the hosts a flicker of hope, it wasn’t enough to prevent the Tigers from slipping to a sixth defeat of the season.
“It was a disappointing afternoon and a disappointing result,” said Bowen.
“We didn’t get going from minute one. We didn’t stamp our authority on the game whatsoever, which is frustrating considering we were the home side.
“Despite that we managed to get ourselves 1-0 up and, if we’d have taken that lead into half-time, we would have been happy.
“We didn’t do that though and they got the equaliser before the break. We needed to regroup during the interval and go again after the restart but for whatever reason that never happened, which again was very disappointing.
“We conceded three in our previous game against Huddersfield and three again on Saturday at home, which isn’t great. Yes, it was two penalties for them, but we should have dealt with both situations better.
“Overall, we weren’t good enough over the 90 minutes. I think we gave them too much respect on the ball.
“We didn’t press the way we normally do and gave them far too much time when they were in possession. We were too passive without the ball and didn’t show the hunger or desire to win the ball back, be aggressive and be horrible to play against.
“We made it too easy for them and, as a team, we didn’t meet the standards we set for ourselves – it was a bad day all-round.
“It’s learning curve for us though and we just have to move on to the next game now and try to put things right.”
Despite his disappointment at the defeat on the team front, Bowen was pleased to end a run of four games without a goal on a personal level with what was spectacular strike.
George Long’s goal-kick was headed on by Tom Eaves and although the 22-year-old wide-man still had plenty to do, his first touch with his chest was excellent. His second touch was even better as he guided a superb left-footed effort from outside the penalty area into the bottom corner of the net.
“It was a nice goal,” he added. “Tom Eaves is a big lad and very physical and he did a great job of putting the defender off.
“I know how ‘Eavesy’ works – he’s going to battle for every single ball and you’ve just got to try and get on the knockdowns around him.
“I don’t know if he flicked it on or not, but his presence affected play and I knew I had to gamble by making the run.
“After getting the touch on my chest, I saw the keeper off his line and just tried to make sure I got the right contact. Thankfully I managed to do that and guide it into the far corner.
“I’ve been a bit quiet in the last four games, so it was nice to get back on the scoresheet – especially with it being my first of the season with my left foot.
“Scoring goals is the best feeling and I want to score in every game I play. It’s five goals in the league this year and six in all competitions now, but I just want more – more goals and more assists.
“My only aim is to work hard for the team and help us win football matches but the fact that we didn’t do that on Saturday meant that the overriding feeling from the game was one of disappointment.”
