Aww, how cute! I might be being silly here, but the colours kinda remind me of German Shepherds, a little! ...Or I could be thinking of a totally incorrect breed, it's just what came to my mind at first glance, haha!
They look very good though! Needless to say, very good work on the colouration, and I like their expression too! Can't quite explain why precisely, but there's just a certain look to it!
Another cool piece, very good work! :)
