I love it! I don't know what I like more, the fact that it's apparently the size of my laundry room, or that you managed to work a flamethrower in there. Well, golly, where to start. I'll just dive in with some thoughts:
1. How big is this thing? If it's as huge as it seems to be--judging by the apparent relative size of the camera and table--it's way, way too big. You just can't light a big space like that. My box is 23 inches tall, and I have trouble lighting it with a 150W bulb and two 150W's. In fact I'm thinking of rebuilding it 4 inches shorter or so.
2. Use 3 lights. One uber-powerful one on top, two less-powerful ones on the sides (so that you really only get a shadow from above). Some of your photos have all these crazy shadows fighting with each other, but you really only want one. If you make a smaller box you can see if you can get away with using the 60W, but really I'd just truck over to Walmart or Home Depot and get yourself a nice high-wattage clamp light.
3. Use cloth to diffuse the light. Cut big holes in the side walls, and drape a white sheet or big piece of satin over the whole thing, and point your lights in at the subject through
the cloth. Or improvise. Our users have used everything from white T-shirts to bedsheets to vinyl.
4. What is that crazy thing on the right? Whatever works, I guess, but for god's sake don't cross the streams!
5. We're seeing some pinkish tinting on some of your shots. Something red in your environment is being picked up and reflected into the box. Try shooting in a dark room, or again, reduce the size of your box and filter your lights through cloth.
6. I came across this the other day--a super-cheap light tent: http://www.amazon.com/CowboyStudio-17-P ... 48&sr=8-11
If you're really having trouble with your box, it's something to consider.
That oughta be enough to get ya back on track. Let us know how it goes...
