Vilth Re-Designs

I have been wanting to create Worlds with really unique races recently, and I realized... I've done NOTHING with the Vilth race from Sil. This is the World that the Field Ravens are from, and they're pretty major characters, so I figured I'd do some concepting for ideas to make their race a bit more unique. These were some concepts I did using Trekkon as a test. I'm not sure how I feel about the colored ears and back design, but I'm happy with how the new face design looks.
