So I have a Raptor!Vriska RP blog (Raptor8itch.Tumblr.Com) and this is the second little doodle I did of her after people kept coming and assuming she was just a dinosaur

But basically the only things that are VASTLY different from just regular Vriska is the fact she's got a tail, raptor feet, longer claws on her hands and feathering on the back of her head and down her back.

the feathering on her head is more like quills (Still feathers) that show her emotions. They flare up when angry/surprised, are at a neutral position when, well, neutral, and smoothed down when pleased or sad
