Not buy, the images show some textures that do not correspond with the final product.
Enjoy this realistic horse (it have unicorn horn) with a beautiful walk :) Try it.
Once painted the texture, change the size to 512 x 256, texture of 512 x 512 makes a bit of blur, but it is easier to paint.
If you don't want the horn, just select the empty space like in this picture, instead of add an opacity. Same for the mane.
the mane opacity, you can use it or improve it to make it better :)
Shadows maps: set them in a new layer in multiply mode
