Great work as always. I don't have any feedback on the illustrations, so I'll stick to what I know - layout.

Remember to keep a clear hierarchy in your layout. Be aware of how different elements interact to create "groups" within your layout. In this example, the walls on the right have a strong sense of being linked, the same goes with the buildings. However the text and moodboard doesn't "attach" to anything but themselves.

What I mean by this is the title "Arakis - Water facility" appears to be grouped with "Arakis - Defensive wall" as if they were describing each other. In this case I think this could easily be solved by the water facility title and the corresponding moodboard switching place. However this still leaves the pinched negative space between the wall moodboard and water facility concepts.

I also think the typeface choice is clashing with the designs - The concepts are all very organic and uses smooth shapes, while the typeface is stylized in a very angular and digital manner. I think some round humanist or geometric typefaces would suit the designs better and work toward better unity. (also sideway text is generally a headache to read!)

I know these things are all second priority, and that you probably know all of this already - but it's what I'm most comfortable giving feedback on! Keep at it!

Nice again! I like that the architecture integrates a lot of curves because it reflects the sensibilities of winblown sand dunes and anything with sharp corners would probably get blown off over time, so the architects would likely take that into account. Post more!
