Thanks Francissimo!
I'm curious, which parts/things make you think of my sci-fi style?

By Diamond
I like the lightning one. What are the two little additions on the main plane?
Hehe, I see I got confused and wrote "thunder" instead of "lightning". Those two additions are not full planes by themselves. The main plane is separated in the middle by a magic fog, and each part have one strange and somehow separate land. To the north of Dreamrift (on the left), a giant magic wall encloses Gladsheim, a prison for the giants, led by the two titans, that had tried to overthrow the gods in the past. To the south of Akarta (the right part here), Kara Tur is enclosed by a wall of flames and vapours. It's a strange place where lies the forgotten dreams and nightmares of the gods.

Here's a small update.
