This Sylveon is a beautiful creature, with incredibly soft and fluffy fur. Its long neck adds grace to its look and its soaring ears give it a majestic air. Its eyes are big and blue, while its fur is a deep indigo color. It has six furry tails arranged around its body. A pink bow rests atop the Sylveon's head, framing its face perfectly.
I recommend coloring the octopus in shades of blue and pink, which are the classic colors associated with the Sylveon. To further emphasize the personality of the pokemon, add some lighter and darker shades of the same colors for highlights and shadows. You can also integrate bits of yellow and green to bring some accenting colors to your piece. For the bow, use the brightest pinks you can find. Finally, the eyes and muzzle can be painted a bright blue for an added sparkle.
