You eyes impish and Mischevious - Tu ojos IMPISH y traviesos
Your laughter's nonchalant insolence - INSOLENCE despreocupado de tu risa

[LearningSpanish]

How about pícaros for impish (eyes)

and ... La insolencia indiferente de tu risa.

But these are just guesses, please do wait for someone who knows what they're talking about jeje :)
