character: sunday_(honkai:_star_rail), surreal gothic masterpiece, Masterpiece, 8k, Honkai Star Rail art style, splash art. Sunday from Honkai Star Rail as an elegant merman. Clear beautiful face visible, golden eyes with navy pupils, looking at the viewer. Soft silver-lavender hair with side-swept bangs, small wings behind his ears, golden halo floating behind his head. The merman is striking a sensual and graceful pose: upper body slightly arched, hands delicately placed on his waist and hip. His torso is pale skin seamlessly transitioning into iridescent scales. Long majestic purple-blue translucent mermaid tail with shimmering scales. Dynamic underwater background, swirling sea currents, bubbles, shafts of deep ocean light piercing the dark water, majestic and ethereal mood, highly detailed.
