Imaginary Topography

I've been sketching some imaginary topographies. These aren't very big and they don't take very long. If I sit and doodle for a couple minutes this is what I get:

Some inspired by real topography, some not so much.

Just playing with shape and density. 

And different pens and smoothness of line. 

And direction, size, shape and spacing. 

I think I'll do some more of these. Maybe add some color and other stuff. Maybe not.

I'd like to end up with a design for fabric but I'm not there yet.

Thanks for reading.
