Designing 2 maps for a mobile game

Hi, We're developing mobile games for several platforms. We do have constant need of graphic works so hopefully this task will only be the beginning. We need 2 "maps" for a war type of game that we're developing. If you've ever player Red Alert or Command Conquer type games, then map is simply the background image that represents the "land". Now, these maps are: - Static images (1600w, 1200h) - First map is expected to be snowy - Second map is expected to be sandy / grassy - Maps are plain (no particular object on it - besides some trees) - Map sizes should be as low as possible - will be detailed Very nice samples that we need (from the famous iphone app): [login to view URL] [login to view URL] What we like about these samples and need in our own work: - Very clear, sharp drawing (no blur, very smooth etc.) - Light tone of green - Small ground fields (light brown parts) - No small details - no old school work - Cartoony drawing Hope I managed to state clearly what kind of 'style' we need. If it goes well, we'll be willing to work together for other designs we need. Please send your previous works as well. Thanks.
