Just a bottle of perfume, rendered in yafray
Nice modelling guy. I would increase the quality in the Yafray settings. Some caustic light may also improve the result. Try to use HDRI, it will give a more realistic result.

Thanks for the comment enricoceric, im already using hdri, method full quality high with raydepth at 20 and precision at 3 and photons at 400000, i`ll add a photon lamp to see if that improve the caustics

Last update of this project, cranked way up of all the settings, different hdri and added a photon light to the lighting to highlight the cauitics
Looks realy nice. I miss a lable on it though!

There`s no label since the client only produces the bottles :|, i also wanted a label in there 
Great result. love the caustics
