Quite good textures! Marsh-texture were not good, but I liked the scattered-trees-text.! (maybe one suggestion for the sc.tr.text.: make the tiles bigger! I think that will give a better look.)
Lovely map and course.. i made a TERRIBLE race, cuz' that i was sitting with sunshine right in my face so everything at the map got very dark.. :S :( Made many stupid mistakes becouse i didnt see the controls :S
