Scotland boss Vern Cotter was left frustrated after his side's loss to Wales at Murrayfield on Sunday and admitted the result was "hard to take".
After several surges on attack, Scotland were eventually rewarded when Jon Welsh scored under a mass of bodies in the game's dying moments and Cotter wants his troops to build on their performance.
"We needed to keep expressing ourselves," he told the BBC.
"Once we started attacking I thought we became a threat. We can take a lot of positives out of the game but we have a lot of things to work on and sort out."
This was Scotland's second narrow loss in two weeks – after their 15-8 defeat to France in Paris in their tournament opener – and Cotter believes there's still room for improvement ahead of their third round match against Italy at Murrayfield in a fortnight.
"We need to improve on our high ball receptions but there is a lot of honesty in the team," added Cotter.
"It is a hard one to take. We were applying pressure and got ourselves in some good situations.
"We will use this game to move forward into the next game.
"We will look at developing our game, developing our counter-attack.
"There were marked improvements and we will keep working away."
