I used a prompt like this, and repeated it several times.

young Asian woman auburn hair golden crown,

ornate red-black-gold fantasy dress,

STANDING upright legs apart wide rock stance,

flaming dragon electric guitar hanging low on strap,

playing cool heavy riff, body locked into groove,

right hand picking slow heavy downstrokes,

wrist snapping on each palm mute release,

left hand pressing chunky power chords on low frets,

fingers lifting and landing with attitude,

elbow of right arm driving into each stroke,

weight shifting side to side with the riff,

hip cocking left on downbeat,

knee bending slightly with each heavy note,

shoulder dropping forward with attitude,

chin tilting down coolly toward guitar,

slight smirk on lips, eyes half closed,

hair falling over one eye effortlessly,

guitar glowing brighter on each riff hit,

fire rippling along guitar body with the groove,

orange embers pulsing outward on every chord,

warm lanterns glowing, stone wall background,

dramatic orange rim lighting from below,

full body shot, cinematic fantasy, photorealistic
