Here, I've done the work for you:
Okay, so now that we've gotten your pictures properly linked, I'm going to be blunt... you have A LONG way to go before you get something solid.
1) Use better lighting and the macro setting (looks like a flower) on your camera. Even most cell phone cameras have this setting now. If you don't have access to better lighting, take pictures outside. Daylight is best light (for the most part). Most of your issues stem from lack of lighting, without proper lighting it makes it very hard to see your minis with the colors they actually have. Just looking at the fire warriors, they seem to be nothing more than black and silver. This isn't a bad color combination on it's one, but you have to provide something else to give shape and depth besides silver and black. Throw some red, blue, anything to break up the very harsh black tones.
I will say this, the best model in your gallery
atm is the Ethereal. You've got nice color contrasts, it's not just black and silver, you've got some reds, some whites, some golds. Better than your standard troopers.
Suggestions:
Go back, add some more colors, work on line control (this is something I still struggle with), and take pictures outside if you don't have a good photo booth setup.
