Rat's Saucy Nest

Finished Sketch of my current project. There’s also gonna be a SFW version. I’m so in love with the crystal ponies’ design. I can’t wait to start coloring it, making the coat all glittery and shiny and everything.

What do y'all think, do crystal ponies have fur? Or becomes the coat crystal-like? It certainly looks like it’s a hard, crystal-like surface, but I also love my ponies fluffy. Doing the little fur-things on the outlines made me realize that it somewhat looks a bit unrealistic like that. And that maybe a smooth surface would be more logical. But after all we are talking about sexualized, candy colored, magical cartoon ponies who sparkle in the sunlight like a 21st century vampire. What would y'all prefer? Fluffy or non-fluffy?
