Gosh darn, this looks amazing. I actually watched it before i read the description and thought "It runs as if it's really big" so that effect of weight works really well But as always, it's beautifully smooth and the movement is so realistic
I love all the details you put into your animations; they seem so fluid and realistic! the slight flexing of the jaw, the ears, the waggle of the horn ornament, everything is in motion! I am especially fond of the feet. I love the kick back of the back feet and how the paws show on the front feet. I suppose one could argue that his feet are really synchronized for a 'realistic' run cycle, but I actually prefer it this way. I think that sometimes creative vision is more important then necessarily ensuring it's 100% 'correct'.
The way her little horn-charm-thing moves perfectly to the beat of her run! How you can really feel the weight of her horns in the way she carries her head! How her mouth is actually open as if panting from running! You know what? This= The only thing I can see that's a little inconsistent are the back legs. When they touch the ground they seem to shrink compared to when they're in the air. (Unless it's supposed to look that way) But still!
