Prompt used to create the image

Scientifically accurate paleoart of Microraptor, a carnivore Dromaeosauridae dinosaur from Aptian times (121.4–113.2 million years ago). Walking with the whole body held horizontal and balanced over the hips like a seesaw, back parallel to the ground, head held low and forward at the same height as the hips, short neck curving forward rather than upward, long stiff tail extended straight back in line with the back. NOT standing upright, NOT a raised head, NOT an ostrich or kangaroo posture. Mouth closed with all teeth fully hidden behind scaly lips, like a monitor lizard. NO visible teeth. Hands held tucked in near the chest with the palms facing inward toward each other, like clapping, claws curving inward and forward. NOT hanging down, NOT palms-down, NOT claws pointing at the ground. Long flight feathers on the hind legs forming a second pair of wings, in addition to the wings on the arms. Reference: Microraptor is a genus of small, four-winged dromaeosaurid dinosaurs. Numerous well-preserved fossil specimens have been recovered from Liaoning, China. They date from the early Cretaceous Jiufotang Formation, 125 to 120 million years ago. Anatomy: a long, low, narrow snout with a slightly upturned profile, NOT a bird beak and NOT a rounded bird head; a short S-curved neck about as long as the skull, NOT a long ostrich neck; clearly visible arms folded at the sides of the body like a bird's wings, with long pennaceous feathers attached along the forearm and hand, and three separate clawed fingers visible at the end of each hand; a stiff, straight tail fringed with feathers along its sides and a fan of feathers at the tip; each foot has a clearly visible sickle-shaped claw on the second toe, retracted and held off the ground, proportionate in size and attached to the toe; body covered in short feathers, tiny, about 80 cm long including the tail, the size of a crow; glossy black plumage with a blue iridescent sheen, like a crow. Full body in side view, whole animal visible, standing in an Early Cretaceous forest by a lake in Liaoning, China, like the Jiufotang Formation, with conifers, ginkgoes and ferns, no grass. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.
