40K perhaps is not really close to what this setting is like judging by applications.  This RP from what I understood was more like a secular, factional low fantasy star wars with Warhammer 40K cultural influences in some areas, especially in psionics but not nearly to the insanity of 40K psionics.  (This is true even if there's someone here who has some features quite similar to a certain xeno from 40K).  

Your martians seem like something from Star Control 2 or Loony Tunes from a stylistic standpoint given what I know of them.

Maybe i'm wrong, but I'll have to see these martians in action to be proven other wise.
