Well if the past is any indicator, anything goes (king of). I've featured 2 collectors so far. Flyguy or Flyguy.net (based in Australia) and Jedi_Randy from Tales from the Mos Eisley Carinderia (based in the Philippines) and their collections. I posted links to their sites and to Flyguy's series of video tours through his collections. Anything Star Wars is great! Action figures, comics, books, art, costumes, customs, props, statues, busts, legos, etc. Whatever is part of your collection. I am slowly slowly putting all of my collection up online in various photo reviews and things. So anything you want to share would be awesome! Especially if you have a website or blog that I can publicize as part of the feature. It can also be non Star Wars things too, but the main focus will definitely be on Star Wars.
I also do photo requests! Scenes you want to see. Figure mash-ups (new heads, accessories), or I can photograph a figure of yours (the colelctor's) that I don't have. Basically you ship it to me, I take the photos however you wish them to be, or create my own poses and displays and send you the photo(s) to you and ship your figure(s) back to you. Then i can publish the photo(s) on AFE in the style of my current photo review series, you can publish them on your pages and sites, and/or you can just keep the photos as a personalized keep sake of your favorite figure(s). I have a professional quality camera and set up with tons of props, accessories, and other goodies at my disposal. There are some photo requests up on the blog already.
I have the most fun with my photos recreating scenes from the movies, inventing new "What if..." type scenes, and building sets and stages for the figures out of the many bits of Star Wars stuff I have laying around.
