I just expanded your suggestion into something bigger than just helping one person with a couple of auctions advertised on the front page here.
I'm thinking more along the lines of Star Wars Customizing-AID spread out over multiple fan web sites. Each site would have its members donate items to bid on. The site that donates the most money to the red cross gets the bragging rights.
The only problem with ebay is that we have to pay the fees on the auctions. I'd like to see 100% of the winning bid go to the red cross instead of just 90%. That is why I suggested we do the auctions ourselves. I sure someone could come up with a page that could track bids. There is probably web software out there that can manage auctions for a web site.
I like the way you brought all of those elements together in photoshop. Reflections of the droids would be cool as would ripples around their feet. I like the spray of water near Ventress's skirt.
Chewie, have you ever heard of a program called Bryce? It's a 3d landscape generator. You can do this same image more realistically in Bryce than you could ever do in photoshop. You could even add some animation to it. The program is really easy to use and creates fantastic images. The program is about $100 but very powerful.
