Guys, thank for your answers... I just want to sorry for my bad explanation before. This is one country of the 18 countries that im planning to draw... im doing one by one... So the water is just for notation. My problem before was about the field color, but i thanks for the observation on the mountains and on the rivers orientation. I have just one more question. I didnt get why the rivers are badly oriented, onde there is no elevation information on the map?

Thanks for all... I'll continue to make questions here, if you guys dont mind!!!
