Kokitsune was my One Piece fancharacter.
In One Piece, she is a human who ate a Devil Fruit (magic things that if you bite, they give you various powers, like turning into an animal. Well, this was Kokitsune's fruit power. But if you ate a DF, you will sunk if you fall in the water). Her model was the KonKon no Mi, model Kyuubi Ryuko. Kyuubi is literally 'nine tails' and it comes from the legendary nine-tailed fox. 'Ryu' dragon, 'ko' another spelling for fox.

The neck, the whiskers and the paws are made of blue-azure fire, the body is yellow and the belly is white. She has nine dragon tails.

As for the dimensions, just think her eyes are big as a cruise ship. :D
