To start off with a “bad” artwork that I came across while searching on the internet. I came across this image.
The exact link is: http://www.museumofbadart.org/coll1/image03.php It is actually a website full of artworks that are considered bad. Personally, I find this image disturbing. The facial features are too intense with the lining and colors. Also, the composition have colors that clash, it does not flow well.
One artwork that I consider is “good” is an artwork by Julie Mehretu, entitled “Mural”
Here is a link to the video: http://www.art21.org/videos/short-julie-mehretu-mural
One reason why I consider this a good artwork is because I really admire the complexity of the work. Although it just consists of just shapes and colors, the size of the composition makes me wonder the effort it took to make this.
