Thanks, and I am really sorry to make you wait ^^
Actually, we are working on 3rd pack already :P
On the first background will be some spaceship, a black hall on the horizon, and other fancy stuff things from our bright future) On the other two, I am still thinking, but one of them might be inspired by Alan Dean Foster's books :)
Also, we have an animator on the team, so when he gets his hands on this pack, I will update it with a few animations for each map.
And again thank you for these kind words, they are very inspiring ;)
