The easiest way to determine the physical differences is to establish the differences between Gaea and Ashadra.


 * Ashadra has a longer day/night cycle so being able to see to see at night is good to have.  This would be the larger eyes trait.


 * As there are multiple types of aliens on Ashadra, they would need to have evolved tolerance to different foods.


 * Some differences in skeleton structure would be present.  As Ashadra has slightly lower gravity, there would have been minor bone mass loss.  Galiana wouldn't experience this herself.

Those are the general differences. Of course, depending on what part of Ashadra they are from, they would change even further. Most people on Ashadra would likely be dark-skinned, but people closer to the poles would be lighter in color.
