From me as viewer i think top hand and the position she is in , gives the illusion that there is either a bit missing from her side (am looking at area next to finger next to little finger top hand)
I also think the position of her head is to un natural which intern is having the effect with her hair , also to me her face expression is one of hurry up iam not comfortable
I feel that the white bg clashes with her white bikini.
Keeping in mind these are only my opinions , from what i see from the image.
Please dont be offended in these comments , I appreciated yours and skips pm on insight of this type of photography , and now look at these images from my new perspective
