Looks like you have some kind of a color separation line just above both ankles
Better poses seem to not have the toes pointed at camera
Move pig-tail so it is not caught under dress collar
The gap between models shoulder arm area and photo border is often referred to as a gutter, because the viewers eyes can fall off the photo at that area
Suggest lower shoulder and roll back as much as possible, move arm slightly away from body and simply fill the void
Other wise this is a great capture
This would be my least favorite
Merry Christmas and Happy New Year
