Ermine in Winter Coat

I drew a white ermine. Ermine is a stoat. In the winter, the stoat's brown fur becomes white, so it can be disguised in the snow. However, it has black tail-tip.
I like stoats, ermines, weasels, minks, ferrets, polecats and other Mustelids very much.
I copied it from a picture.
Watercolors and white acrylic on paper.
