Not exactly like Asgard, just the whole general feel they had: Golden buildings, distant stars and planets, eternal sunlight.
As long as the rumors of the Heaven-wide beer shortage are inaccurate I don't really care what it looks like. It will look good enough.
I certainly wouldn't mind if it looked like Asgard. Though the descriptions in the Bible of it being a massive Cube made of precious stones with a sea of glass, golden streets, God's throne providing all light, a bunch of angelic beings flying around all the time, etc... leads me to believe Heaven will be beyond our mortal abilities to visualize. A bit like the end of 2001 where Dave is flying through the Monolith.
As if anyone as singularly sinister as Lord Licorice could get into heaven. His diabolical dollops of confectionary-based chaos rank him amongst the most fiendish foes in all boardgamedom.
Actually, a great number of fictional cities don't leave much at all to people's imaginations, since the creators are quite explicit about its layout and aesthetic. To demonstrate the problem with your quip, please note that while fictional, an X-wing looks nothing like a blimp. Nor can you say it does "in your imagination." It looks like one specific sort of ship, with four wings that have a particular symmetrical layout that are the thing's namesake.
