"I'm satisfied with the result, satisfied with parts of the performance but it's not any better than satisfactory," the 38-year-old told the club's website https://rangers.co.uk.
"I think there are a lot of positives to take from the game... but one concern would be that we didn't win the game a lot more comfortably and put the whole tie to bed tonight.
"I thought we created enough to win more convincingly so we're still in a tie, we're still in a game and there is still a lot of work to do."
Rangers will travel to Macedonia for the second leg of the tie on Tuesday followed by a friendly against Wigan Athletic before opening their Scottish Premiership campaign against Aberdeen on Aug. 5.
