Map and assets artist for a video game

We are looking for a talented artist/graphic designer who can create a game map, textures, and assets in a certain style. At first we would like to create a map. You can see the style of drawing/colors (we like this hand drawing style) in the reference samples. As you could see, it will be a game with the view from the top, but based in mid-eval Korea, so the style should match the settings (e.g. Korean architecture of that time etc). If you send us your small trial to show us what you can do and we like it - we will proceed with you for the full map and, later, the character/assets development.
