The gif is smooth but overall I find it meh (the sharp angle of the shoulder is bad and the spacing of the legs is odd). My biggest thing is actually the tags and title. Futa, short for futanari - a Japanese word that means "hermaphrodite". It seems that you are using the variant of Sheik that has Zelda completely change her body to that of a male and not the cross-dressing one, and there is a severe lack of a vagina.
Very nice. ^_^
