A late header from centre-back Jake Buxton sealed the points for the Rams, who moved up to eighth place but incredibly are not yet completely certain of their place in the Championship next season.
Although it would take a very strange set of results to see the teams below them all go past by the final day, Clough wants his players to retain the focus they showed after a poor first-half performance and finish the campaign on a positive note.
"We showed immense character but we should have done a bit better in the first half," Clough said.
"We were comfortable but we should have done more to get a goal in that spell. It took Leeds' goal to get us going.
"It was a great save by our keeper Frank Fielding from Sam Byram at 1-1. Frank hasn't had much to do in the last couple of weeks since he has come back in but that save was vital and I thought if anyone was going to score in the last 15 minutes or so it was us.
"I don't feel we are safe yet, but we want to finish on a high and get as many wins as we can."
