Guinness painting

Ciaran and a friend were having a bar room chat recently about painting.  His friend said he didn't think what Ciaran paints is art. Ciaran disagreed!  

The friend then plonked his pint of Guinness on the bar and said that if he could paint his pint he would believe that what he does is art.  

Ciaran loves a challenge- he took a picture of the pint and this is his progress.  

What do you think?
