ACHTUNG. References

The ref is getting old.
I did some corrections:
1) Konrad now has a darker color of hair plus his fur must be a bit more ginger. His palms and soles are white, his chest is more like beech martens have. And he has more marten-ish face, longer and keener.
2) Saveliy's fur is almost grey, maybe a little bit blue.
3) Marsel has another markings, I'll try to give a pic later.
