Tyrannian: While some insects do have fur on their bodies (such as moths,) something that beetle-like should not. The fangs are also completely un-insect like (insect jaws are much wider and have toothed ridges on the inside - I can't think of any species that would have teeth like that). At least the color palette's decent.
Gold: Pretty standard for the color. It looks reasonably metallic and the shading on the legs is particularly well done.
