First pictures of Dota 2?

Valve's Dota 2 will be officially revealed at Gamescom this week, but it looks like a couple of screenshots have leaked out in advance by a Chinese website. All the teams that will be competing in the big Dota 2-tournament held at the convention have had access to the game ahead of time, so it's probably through these channels the pictures have leaked to the Internet. Check them out below, unless you don't want to get spoiled somehow.
