What I enjoyed most in Melbourne was the variety of styles. This piece was directly opposite the top one, totally different style, but still excellently executed.
The St Kevin's Arcade ones are a Cut Collective/Misery project. The two in the first post are both Component pieces. The other 3 are by Misery, Component, and Enforce 1, respectively.
One of my favourites, now gone of course, is another of Askew One's pieces.
