Shaun Maloney admitted the 6-1 win over Gibraltar was a case of "job done" and little more, acknowledging June will bring a greater challenge in the shape of a visit to the Republic of Ireland.
Maloney scored twice from the penalty spot, taking his tally for the campaign to four.
Despite the emphatic victory, he was honest in his assessment.
"I don't think there was too much to be happy about - or the other way," Maloney told BBC Scotland.
Steven Fletcher scored a hat-trick and Steven Naismith also scored as Gordon Strachan's men secured their biggest win in nine years.
"There were times today we played well, but obviously the manager's said there were times we didn't or when he wasn't as happy," said Maloney.
"But 6-1, I think it's just a job done. There might be a bit of frustration there were a couple of chances left out there, but I don't think we should be overly disappointed with the result.
"Over the last 18 months you can feel the group getting stronger. I don't think we've taken massive steps in this gathering, but in the last 18 months there have been some pretty big improvements."
The result keeps Scotland in a strong position, though Group D remains wide open, with Germany, Poland and the Republic of Ireland also vying for qualification.
Martin O'Neill's side host Scotland in the next qualifier, a match that could prove pivotal to both countries' hopes of reaching Euro 2016.
"It's going to be a huge game, crucial to both sides," Maloney said of the clash in Dublin.
"The pressure will obviously get magnified the closer the game comes."
And Maloney paid tribute to his fellow forward Steven Fletcher who ended his own international goal-scoring drought by scoring the first hat-trick by a Scotland player since 1969.
"It's a brilliant day for him - I was told about the long wait for a hat-trick - so for him to get that, it's been a great day."
