2D Side-Scroller Game Environment– Fantasy MMO Asset Kit (per level/world)

I am building a 2.5D side-scrolling MMORPG and I need an experienced 2D game environment artist to help create the first proper environment asset kit for the game. The player character and companion are already in-game, but the world/environment art needs a major upgrade...
