Design 2d tiles and sprites for a video games

Hello, I m developping a video game and I need a graphic designer for making 2d tiles and sprites. My game takes place during the middle age. It s a fantasy universe with cartoon style as super mario or rayman. the target audience is children. The game should look like an old video game. Then the tiles are only squares and characters should fill a square or a rectangle. Please send me your last projects if you apply. Thanks
