I am forced to agree with you that it is an impressive artwork. but that's the thing that is so retarded about art. how can some baby put some colours on a canvas and its the best thing since sliced bread, when there are pieces like this around. It's tooo subjective that you could actually do anything, because somewhere out there, someone will call some weird piece of crap art.
I dont agree with this, but let me try to explain the whole 'baby like abstract art' idea. As people age, we are affected more and more by our surroundings, we do not make decisions based upon what we feel is right, but rather what is perceived to be right based on how the action/consequence will be veiwed in our surroundings eg: our friend, family. We lose the ability to make decisions purely because we want to.
When a child paints a tree, they do not consider how others will veiw the painting, they do not care how it will be veiwed, it does not matter what the tree looks like, they are painting a tree the way they want to, it is purple because they want it to be, it is angular and squiggly as that it what they want.
This is what abstract artists often try to capture, they attempt to let go of creative inhibitions and 'just paint' as children do. Hence why people may see an abstract work and say "A child could have painted that, what a piece of junk". People cannot make adequate judgements on what they do not understand.
