DOTA 2 characters at a 'Fails of the Week' stall HD Wallpaper

Four stylized DOTA 2 characters are depicted in front of a market stall. On the left, a blue-skinned character in a sombrero looks distressed. Next to him, a vendor gestures upwards. In the center, a knight in blue armor runs, and on the right, a chained man with an axe laughs maniacally.
