The details on this piece are varied, bringing the viewer's eye towards the face of the Anchiornis. The use of bright reds against the darker feathers on the rest of the body also help draw your eye upwards to see the cute expression on this tiny dinosaur's face.
Behind the main subject, to the right, the leaves are highly detailed, matching the level of polish as the scaly beak on the dinosaur. The less detailed trees to the right are uninteresting, however provide lovely depth and fullness to the whole image.
Overall this piece feels complete and surprising, as we watch a bright eyed Anchiornis munch a prehistoric insect snack.
