Bad Brain says he's new to the Quake III skinning scene. My first tip would be to use a better template for the readme file. Just download any other skin and most likely you'll find a pretty comprehensive readme file. Just change the relevant information to suit your creation, and you're set. For a first try I think I Madman is a nifty little skin.
Nothing stands out or looks out of place in the skin, which is good.
The should be available on polycount. They're invaluable when attempting to make original skins. Once you've got this down pat, try to work some detail into the skin. Instead of using color, shading, and highlights to get the effect across to the player, use detail. Mind you, this is easier said than done and simply comes with a lot of late nights, coffee, and sometimes even practice.
