This is a demonic entity that lives a kind of dragon-like existence, inhabiting a private cave or other lair where it alternately secludes itself or demands food offerings and terrorizes locals. It's also a demon of mostly gluttony and sloth, which in most settings means some sort of big, bloated pig-slug sort of devil, but is averted here with a spindlier, faster looking design. I like the cute black eyes on a head that reminds me kind of an ant, with that weird beak and the various writhing protrusions. Its forelimbs are also cool, with both the ragged-edged arms that come across as bird-like and the mantid-esque talons branching off from them!
