After the second round of edits, feedback was given that:

hierarchy/ negative space needed to be stronger
smaller text/ text did not have to be so huge to show emphasis
sweet spot of placement – the placement of the text was a little awkward and clunky
placement of mosquito bite – not very realistic

Feedback was also given that the image still looked too sexualised, despite the cropping.

 

Thus, I made some changes to the layout and central image to create the final:

The central image was changed into something more neutral, although the same treatment was applied to it.

The placement of the main slogan was changed as well, leading vertically along the neck of the female down to the mosquito bite, to create some kind of flow of reading for the eyes (instead of being a static horizontal block).

The secondary slogan and extra information were kept to the right of the poster (but not flush left) to continue on the reading flow from the mosquito bite, but still ensures that the text is easily readable.
