RPG MMO game graphics

hello guys ,
we are currently making an RPG MMo game
but i havint found any designer to make them … i need to know
how to make maps and etc for the game
its a 2D top-down game

You could start by drawing the basic Idea of the map. Then make some of the larger assets such as buildings and trees. Then add the detail such as boxes or plants scattered around.

As KingMathew said. Start by designing the terrain (river, forests etc) then add the bigger features such as buildings and big rocks etc. Then get smaller and start adding the things like boxes.
