Galaxy held above hand digital painting

One human right hand appears in the lower third of a vertical 2:3 frame, palm up and fingers gently curved, occupying the center-lower area with wrist and sleeve visible at the bottom edge to preserve the original crop and framing. Above the palm, a single luminous spiral galaxy hovers tilted toward the right, filling the upper half and extending from center to the right third with distinct bright core, looping arms, and scattered star particles. Render as a polished digital painting with smooth skin textures on the hand, subtle knuckle creases, fine reflected blue rim light on fingertips, and faint skin pores catching the glow. Light is cool and directional from the galaxy, creating soft rim lighting and deep blue shadows on the underside of the hand while preserving gentle ambient fill in the background. Background is deep navy space occupying roughly the top two-thirds with sparse distant stars and faint nebular haze concentrated toward the left to balance the composition. Foreground elements include delicate floating particle sparks between palm and galaxy and thin ethereal trails that connect the galaxy arms to the hand surface. Resolve the galaxy with luminous bands of cyan and electric blue, tiny pinprick stars, and a warm off-white core that casts subtle spill onto the palm for believable contact. Keep overall mood majestic and serene and frame precisely for a 2:3 wallpaper crop with negative space above the galaxy and tight lower margin to emphasize the hand-to-galaxy relationship.
