Chara as the angel, because I think they're neat
Image description:
Undertale fan art of Chara. Chara is a small human child with pale peach skin, short brown hair, a long-sleeved green shirt, and dark shorts. Their eyes are hidden by shadows and the rest of their face is mostly hidden by their hair and by the bouquet of golden flowers they're holding up in front of them, with the bare bundle of green stems sticking out beneath the blossoms.
Directly behind Chara's head is a four-pointed yellow save point "star", looking like a crown or halo. Above and behind this save point is the word "Save" in all-capital letters and in rainbow colors. The background behind "Save" looks like a muted rainbow sky.
There is a pair of massive angel wings spread out behind Chara, white but faintly tinged rainbow colors. There are ruffles in the wings that look like feathers, but also give the wings a look almost like papier-mâché, like an art project an ambitious child might make. These "feathers" are being blown off and scattered from the bottom of the wings, where they're blown into a black void and seem to be turning into golden flower petals.
Under the wings, the background now looks more like the sky at sunrise. This background is cut off at Chara's knees and becomes the black void where the golden flower petals slash angel feathers are scattered.
