From the announcement:
Hey Wyrdos! Today begins one of the most exciting painting competitions of the year: Iron Painter.
What is the Iron Painter? The Iron Painter is a multi-round online painting contest conducted by Wyrd Miniatures. It is a long, grueling competition where painters will be tasked with continuously producing a series of painted models within tight timelines. It is not a competition for the faint of heart (or brush).
