okay, that's cool, but try using the space and light you have more effectively, there always are more limitations than one can imagine. If you shoot faster and power down the flash, you will get more drama, better, softer light and an overall more appealing shot. This of course means you must shoot manual, which is no big deal, in fact if you dial it in it's more consistent anyhow, an I shoot nikon's which arguably have the best, most accurate and versatile flash systems of any dslr. . .

If i were you I would try the DEMB flip it, it's one of the best and most portable units i've ever used. If you want you can use it as a diffuser or a bounce card, or both, and it warms the light very nicely, sometimes too much, however if your shooting that close, it would work wonderful, and the way it's designed you dont need a fancy flash bracket, although I usually use one. . .

BTW, it's a lot better in my view than the gary fong unit which i also own but dont use. . .
