In all honesty, its a very cool idea, but the lighting from the tablet is really whats hurting them the most. If you invested in a couple Lowel i-Lights or a Lowel Blender, you could make these look a million times better. They really arent that expensive and can be found on eBay a lot of times for pretty cheap. The lighting on the statues just looks flat. Also you should think about making some mini reflectors. This image is the perfect example
Had you bounced some light into the left side of her face, it would have looked much nicer. As is, it just goes black and you cant even see her eye or her mask. They can easily be made by buying some foam core and cutting it down to size. You really don't even need to bouce light into them alot of times. Just sticking a white piece of foam core just out of frame by the dark side of her face will bouce some light in there.
All in all a very cool idea, one that could be taken a LOT farther quality wise with just a few purchases. If your this interested in doing pictures like this, I highly recommend doing so. You wont regret it.
