Impossible landscapes 1

Here is my second attempt at delving into abstract forms world. This time I have decided to try my strength at this popular "topographical" (I don't know if it has any name) technique, and check if'll be able to spark something good from it. I must admit that I am pretty happy with the result. Enjoy!
