These first two are examples of 2D animation with a potentia;l character study on left and an environment fly through on right.

The next pair has a "Google Earth" fly in on left of a stylized Lego world, the right is a character study for a low poly 3D world.

Next, a variation on the fly in with a map and a 3D low poly fly through world on right.

Here is a realist earth zoom on left with a solar system fly through on right.

On left a 3D low poly earth zoom and on right a distinctive variation on the theme.

Finally, a 2D earth zoom, very toonish, ending in clouds which would then transition into whatever environment we are dealing with.
