I like what you've done with the dowels to create different levels. It's a great way to take advantage of limited space.
Yeah, that's a really good idea. Placing them on tiered rows like that looks really cool. I love group shots, and this method gives them depth as well as width, without the usual sacrifice in visibility.
Deorum182, one think that you might think about is finding some thicker, black supports, rather than the thin white columns. If you found something as thick as the stands themselves, you might even be able to make it look like they're part of the stands (i.e., some stands would just look like they have a natural elevate base). Something like that would really step up the class of the display even more.
Anyhow, definitely something I'll have to think about. I use bookshelves, so there's not the opportunity for as much depth or as many tiered rows. But I'm running out of room - maybe if I figured out how to add one layer of rows to each shelf, I could increase my capacity by 30% or so. That might be enough to tide me over until TDKR.
That's a cool Two-Face. I like how you modified the Hot Toys Eckhart head - a totally new twist on an already existing head. The figure and sculpt have got a lot more color than the movie, but without being gaudy in the way that some comic book figures can be.
