It's based on a map from TF2 with the iconic RED team's base. It was actually a bit more detailed, but I pushed the simplicity as far as I could go. Following KISS to the extreme definitely made this design stronger. Since I did a RED poster, I thought it was only fitting to do a BLU poster and then decided to make a series out of it because it was fun to do...
Since the payload gamemode centers around BLU pushing a bomb cart to RED's base, it was only appropriate for a BLU poster to be a payload map. I was going to do the map Gold Rush, but the word "Hoodoo" looked much more interesting and hoodoos make some interesting silhouettes. This was the second one I started but the last one I finished due to many changes in the hoodoos and payload cart and attempting to add depth through silhouettes.
I thought the colour grey was appropriate for Sawmill: the map is raining, it's king of the hill so teams fight for one point, and the annoying two saw blades in the map are obviously grey. I originally made it look like one blade was in the foreground and the other in the background but it looked too chaotic so I simplified it and centered everything since the contested point is at the centre of the map.
Doomsday is a map that involves the teams fighting over a briefcase full of "Australium", a fictional gold like substance so I thought yellow would be appropriate. Along with the rocket having a yellow cap and highlights and it being commandeered by a monkey astronaut named Poopy Joe (the space program's logo is also of a banana).
Wow, TF2 sounds extremely ridiculous when explaining it...
Anyway I might continue this series later on since I do still have some ideas and the big update is supposed to hit today so I may get even more awesome ideas.
Well time to wait for the update, I can't wait to kill an army of robots.
