Intro Page web design for Browser Based Game

Searching for an artist who could make an outstanding intro page with a little animation for browser based game. The game is about crimes, mafia, war between cities. Environment in the game is modern times (not old, so no gangsters). It should have some animated elements, login and register forms. Responsive. On desktop version background should be animated and in mobile version it should be still. Your more ideas are welcome. Examples that i like and should be similar: [login to view URL] (i like that animation idea) [login to view URL] (i like that style in which it is drawn) [login to view URL] (i like that animation idea) IMPORTANT!!!!: If you bid on this project, show me your protfolio of animated matte paintings backgrounds :)
