I had two eevee's and I bred more from them, but didn't evolve them. I wanted them to be my two little eevee's and I didn't want them to change. I loved them the way they were. is adorable! And the art is fantastic.
Pokémon - Umbreon was designed to be light in the dark, and this concept art captures it as the viewer can see a glowing yellow with a glossy black. The yellow shapes are so very solid rings but the rest of its body is uneven and graceful in shape.
