Then finaly i found another hdr image at https://hdri.3dweave.com, so for now result are here

I would like eventualy to create ice environment and to have water drops on can, but im not quite sure how to do that, so i'll keep on playing. If you have any pointers for realism, they would be much appreciated.

i have only one ambient light with no intensity

Can shader should be much like coke can(i shoud buy it so i can stare at it), upper cover is from thin plastic, and peel off cover is basicly lambert...
