Kind of like the world is not necessarily a bad thing- but if it's not what your going for, my method for drawing different worlds is to start with a single geographic or political feature that can define the world. A hypothetical example of this in our world would be the Mediterranean; an inland sea around which most major civilizations develop. Make two large oceans barely connected by a single strait of water; whoever controls that will control the most important trade route in the world. You draw a thin strait, and then expand off of that, drawing chaotically and unusually.

The base of this strategy is to avoid drawing "continents", which we will always subconsciously make to look like the ones on Earth.


My second strategy is far simpler. Draw by hand, with a pencil, on regular printer paper. If you are already doing this, relax your mind and let your hand wander without much guidance. Try to avoid angles of 90, 45, and 60 degrees.
