Can't see much but the bigger models are looking good! Very nice muted/dirty tone. I like my Bad Moonz to be bright and shiny but I appreciate the different apprach!
If you're looking for an alternative to just red Martian Earth you should check out the GWTV youtube channel. They have a tutorial on how you can use it to make a good looking lava base.
Also where did you get the mek/vehicles in the back? Are the
FW or kitbashed?
Keep up the good work!
