Based on the skeletal reconstruction made from Scott Hartman.
The colors are based on the bearded vulture livery, with some variations.
The feathery toes are based on Matt Martyniuk's post on dinosaur foot scales, which indicates that scutes may have evolved from feathers, rather than the opposite.
Other reference took from the usefull blog of Andrea Cau, Theropoda.
