I see a distinct problem with the terrain model. It seems to build the physical shape then apply a waterline to define the islands. That makes the above-water island a simple extension of the below-ground terrain. Earth, and I think is safe to assume any planet with water, is more complex.

Before getting to vegetation and biomes, why not some modeling of increased weathering above sealevel? Unless every island is tropical and volcanic, those mountains should be flatten out significantly in comparison to the terrain below sealevel. The deep valleys should fill with gravel.

Unless the game is letting you explore underwater, why bother? And even then that still seems excessive.
