I'm making a Tremulous wallpaper and I'd like to hear your opinions before I proceed further and add characters and logo.
My questions: Should I add logo at all? I will probably not be doing a different background, this took quite some time, but I can adjust it heavily. Would you like it darker? I will probably calm the lightning on the ground to give more focus on characters. Speaking about characters, what kind of protagonists would you like to see?
If you'd like the sky in different color or if you think there should totally be a battlesuit (or any other suggestion), just post.
