I'll put these up here too. Just some ideas. They are figure focused but dioramas could be worked in. I do agree with Remco, I'm set up more for 3-3/4". That's where all my fodder is. I wouldn't do 6", so if we could do any range of sizes from 12" to 4" that would be cool.
Golden Age EU
This would encompass Marvel Comics, The Holiday Special, Ewok Adventures Live Action TV Shows, Droids and Ewok Cartoons, Del Ray Novels from the 70s and 80s, News Paper Comic Strips and anything pryer to the Dark Horse take over.
Star Wars Crossovers From TV and Cinema
How would your favorite characters from TV and Movies translate over to Star Wars? Anything from Barney Fife to BA Baracus, Walker Texas Ranger to the Walking Dead, Jason Borne to Jason Vorhees, The Good The Bad And The Ugly to The Avengers. YOU CHOOSE!
Directors Cut
Who is your favorite Director past or modern? Every Director has a certain visual style and flare. If Ridley Scott were to have created Star Wars it would look a lot different! What would your favorite Star Wars character look like if another Director would have gotten a hold of it? Howard Hawks, John Ford, Ridley Scott, Martin Scorsese, Stanley Kubrick or James Cameron... the list goes on.
I'm with the Band
Who is your all time favorite band? What's your favorite type of music? Create a "Star Wars" style band, chorus, crooner, composer the sky's the limit! KISS as an alien rock band! What would Motart look like if he were Rodian? Put your creative thinking caps on!
Exotic Beasts from around the Galaxy
Create a small furry animal from Hoth. Make a scaly, slithering beast from Mandalore, or maybe a creature from a deep fresh water lake on Yavin 4. Your imagination is your only limitation.
Halloween Extravaganza
Take a favorite character or feel from your favorite horror or thriller and make a Star Wars Villain: Bounty Hunter, Sith Lord, Crime Lord, Mercenary or just plain Scum! Universal's old movies, Freddy Kruger, Hammer Horror, Hannibal Lecter or if nothing else just an excuse to make another Zombie Trooper! I love Halloween!
