Cover Demo CD

I need a cover for my band's upcoming demo CD. The musical style is melodic heavy metal, so it should have a look that fits a heavy metal CD. The theme can be one of the following: "Hunting Angels" Scarcely dressed she-devil on the foreground with a rather large machine gun in her hand. In the background (ground and sky) we see demons slaughtering angels in front of heavens gate. Sky is crimson red. Should be busy, but not too busy. Think early Iron Maiden album covers. "The Cuerdale Hoard" Wide shot of a river bank. Workmen have just discovered a treasure chest made from wood and lead, and filled with "hacksilver" and coins. Weather condition is rainy and gloomy. Time of day is duskfall. May be painted, drawn, rendered wireframe, photoshop composition... It really doest matter. As long as it looks cool as hell. Preferred theme is "Hunting Angels".
