Lewis Grabban put the visitors in front with a penalty early on in proceedings before Jayden Stockley stroked the ball home before the break.
The draw sees Forest five points safe in the play-off places whilst North End are two points off the pace.
"Preston played with their quality, they lost their defender early just before the break and then Pearson after," Lamouchi said.
"That's two big changes. But I like the manager, I like the way they want to play.

"It's absolutely different to use and they're a different team in this league. It's not easy to take a point here.
"It was a good point, I'm happy with it and I'm happy with the performance."
Thought the Forest manager is happy taking a share of the spoils from Deepdale, there were parts of his side's game that he didn't like, noting that his forwards got very little change out of the PNE backline.
He said: "We've played in the same week with the same dynamic but different quality and here it was different.
"There was the long ball and the second ball. It was a good job from the boys, they never gave up, they stayed in the game.
"They're tired but we need to keep going and this point is a good point.
"Unfortunately with the ball we made a lot of mistakes, we didn't play with confidence, passion and we played long like Preston. It was wrong.
"The defenders from Preston didn't give a chance to Lewis [Grabban] or Nuno [Da Costa] or Sammy [Ameobi]. It's a good point, they're a good point all the best to them."
