Note: This is purely what I perceive from the image.
The vibrant red colors really contrast well with the stark whiteness of the bath tub, but what really captivated me is the model's face. Centered within the vibrant reds is this paler face caught mid-scene with near child-like innocence. The red surroundings help mark out the tinier details of red in the rest of the shot (i.e. the lips, the nails, the objects) and help create this While I cannot really tell what the model is holding in her hands, the object looks almost like a red toy car and a ball or a flower petal. The image of the model covered in suds doesn't reflect a mature female portraying some 'seductive pose', but the image of a youth caught mid-scene in bath-time. The suds tastefully cover the model's body, which I feel eliminates the entire feel of trying to be seductive, but create a different portray of the body. The suds do not even give hint of how 'developed' the model's body is, which in turn masks her true age. Note how the model is posed more comfortably and more focused towards the small object in her hands. Her mouth is slightly agape, but in more concentration than anything like a child trying to focus on a certain task. Combined with the half-closed gaze, this adds to the expression of concentration more than 'seductiveness'.
Overall, that's what I perceived from the image. Nothing seductive, but due to the semi-nude factor it probably required the maturity censorship. It is an attractive image, in some sense, but I really do not see the 'hotness' the model is apparently establishing.
