Try using no flash then, use two continuous lights angled from the sides and diffused, those little clamp lamps you get from the hardware store are a great way to experiment with different lighting techniques on a budget, and those white vinyl table cloths you get at the dollar store make excellent diffusion material!

Agree with locksmagic....The flash is of no use in such kind of images. You can try light sources like mentioned by locksmagic or else you can change the settings in the camera for the exposure....

Nice try with this, it was impossible for me to get even one good one to enter. GL to you!!
