I think the tightrope walker is a bit too large; maybe 70% of its size 
should be a better fit.

I'm not so happy with the Earth, Mars, red-white striped, and 
yellow-orange banded balloons; they look as if they didn't receive any 
sunlight, while instead glowing on their surface.

If this is supposed to be glow from the propane burners, it should be 
(1) darker, (2) more coloured, and (3) be more intense near the bottom 
of each balloon. One way to achieve this might be to place light sources 
at the propane burner locations with proper distance-based falloff, and 
use arse... um, I mean, backside illumination on the balloon skins 
("diffuse X,Y" or, better yet, "diffuse albedo X,Y", where X+Y < 1).
