Barbed Reptile Alien

Hey gang!
Here is the fourth character from my new (still unnamed) series, based around an intergalactic battle royale! The event happens roughly every 50 years with each species fighting for control of the resources of the universe.
My brother Sam and I are working together on this one, really enjoying building the concept together!
This is the Barbed Reptile Alien, they are covered in razor-sharp spikes that they use as weapons against opponents. Due to their extreme regenerative abilities, they can break off the spikes at their wrists and regrow new ones in a matter of minutes!
Let me know what you think!
