Kevin Federline gives his performance at Sunday's Teen Choice Awards the thumbs up, he tells PEOPLE in its new issue.
"I'm happy," says Federline, whose first album is due in October. "I think I pulled it off pretty well. (But) I'm overly critical of myself."
Federline closed the show with a performance of his song "Lose Control," introduced by his wife, Britney Spears. "This show has been very good to me and my career over the years," Spears said onstage. "And I'm hoping that it will be as good to our next performer."
After the show, Federline tells PEOPLE, "We went straight from there and jumped in the Ferrari and took off. (Britney) was happy, she was proud. … My whole family and everybody was there."
While he says he'd like to improve his stage presence, Federline is looking forward to remaining in the public eye.
"September 5 we're launching the video," he says. "There's a lot of good things going around here."
