how many times have we seen this before, some artist grabs headlines for a little while by making a controversial piece of art. with mother theresa, the pope, Christ, mohhamed etc.etc.
that said it is a visually interesting piece. contemplative pose, strong lines; respectful if you ignore the composition.
i generally have a very poor opinion of most modern "artists" but this isnt in the class of feces/vomit smearers and others who have little to say but say it loudly. and i would say it is above the level of mad magazine characitures, but i wouldnt expect to see it in the whitehouse
