think you need to work on your lighting a little bit more.
if you look at the model you can see the light is coming from the front left above the model
The bath is lit from above left but at a harsher angle.
On the other hand i really like the hand prints, a touch of colour in any black and white photo can really make it pop and you've done a good job here
If you want to get some decent (well for free) software for your models, you should look into Daz Studio.
Sadly you have to pay for the models and clothe but with the right stock (i find catalogues really good!) you don't have to
