The sidelighting isn't doing much for you here except throwing a shadow on Leia, and Darth's pretty much disappeared against the black bg. Shooting from above has emphasized the smallness of the pez dispensers. There are probably more dramatic, interesting ways to shoot this.
The pez need to be set up so you can see the Ewok behind the Yoda, and the C3PO on the left.
I think your light is too harsh on the right hand side, the shadows from the "dark side" are too strong, plus there is a shadow on Leia that is cast from Yoda. Try some fill in light on the right. Your backdrop cloth is too wrinkly.
Fantastic potential here. Really. Just looks rushed.
If you use a backdrop iron the wrinkles out. and make your fabric folds subtle. Table top lighting needs to be more than one source unless you go for a very dramatic shadow effect...
A big pile of pez in all colors with some zany cross lighting would have added to the drama. Get several flashlights for cheap spotlighting effects and even put colored plastic on the flashlight for some cheap effects.
dah, dah, dah dah dah dah, dah, dah dah, dah... ok - I realize it doesn't translate into text very well. but I tried. Are those original? They must be worth a bob or two.
Wow, you have quite a collection there. A little bit more focus and light, and a smooth background (I have found that black cardboard works best for me) would improve the shot IMO.
The lighting on this one needs some work -- I can see all the rebel faces, but the empire faces are so dark I only know it's Vader because who else would be a big black blob. I also think I would have worked on the composition a bit more -- some of the rebel pez dispencers in the back are being covered up by ones in the front. Same applies, a little, to Boba Fett and Vader. Overall, though, I just don't see this as much of a game.
