After a year or so away from Joedios I'm just getting back into taking/posting pice but I remember WW as a great idea to make you think of new things!! Anyway I have a few ideas for future themes... (some have been done before)

Secondary Specialities - characters using their secondary speciality

Song titles - a pic based on the title of a song.

SFX - a pic with some special effects in - could be digital (photoshop etc) or real - lighting, fire, etc!)

Unlikely Allies - sometimes the enemy of your enemy is your friend!

Crossovers - always a good one!

Wildlife - a shot featuring animals (could be accessories like "Polly" or "Junkyard" or real animals (people's pets etc)

Historic photos - recreate an historical photo using figures (for eg a photo of WW2 troops recreated with Cobra troopers or Joes in identical poses)

Oops! - a photo of things going wrong (from the silly to the deadly!)

Hope at least some of those ideas make sense and are of use!!
Cheers
