so i edited it, i tried to make sense here so.
here applejack came walking with luster dawn as she sang her part of the song, she then she leaves luster and stands at big mac's side as she finishes her line, it works for me LoL
and since i recolored little mac
and changed his mane a bit so it would make sense for applejack to be his mother, let's call him macjack
or little macjack
