working on smutty pictures

I was asked by the M Galery in Wrocław www.galeriam.com to take a part in a group exhibition in May. The show will be called "Świńskie obrazki" which means as much as 'smutty pictures' (verbatim: 'pocine pictures').
I'm still working on, but part the work is partly finished, so I though I would show what I've already done. So there they are:
a man

 a couple

 and a granny
