I just wanted to say likening 'abstract art' to music is wrong. The guy's initial reaction to label those prints as "what the cat threw up" was on the ball. Abstract art is not like music because music follows mathematical rules. Abstract art is like recording farting in the bathtub. Its easy and its stupid.
A clear example of following/not following rules is modern abstract architecture versus classical architecture (both don't try to represent something). Classical architecture follows mathematical rules. There is repetition of shapes, symmetry, hierarchy, ratios etc. You can tell how big a building is with a quick glance. With modern architecture they don't follow these rules, its usually an ugly box with crap whacked on it. You can't tell how big it is and often where the bloody entrance is. Classical architecture probably followed rules possibly because its easier to build (eg. calculate how much material) and easier to defend in a battle. But it just looks better as well! You only think differently if u have been brainwashed by paying a lot of money to go to art uni or if u can't draw or if u think liking sh*t means you are smart.
I like comics, picture story books, portraits, caricatures, paintings of battles etc. as long as they are done well. I don't know which fall into the categories of illustration or fine art.
