The wobbly panels didn't bother me too much. That looks to be what would happen to them anyway. (sort of thin, untethered sheets of plastic/glass) Plus, the Hoth base looks even more slapped together than the one on Yavin. Heh.
One thing I'm sure Ady will do with those panels is add something like graphics to them so they don't look so lifeless. At least when they're not wobbling.
