My brother recently uploaded a Lego MOC, The Pilgrim's Progress. His rock technique (as well as the ones I've seen here) have been so cool that I was convinced that I should try my hand at one.
About this creation
This all started from my experiment on rocks, as well as the fact that I've been itching to build something. It is a duel scene with a micro beach and cliffs, and a minifigure-scaled scene on the right. The idea, mainly, was to practice building rocks. It is also an experiment on the texture of the two different rocks which coincides with the two landscapes. It is basically an experimental MOC, something I threw together (though not in 20 min.) I'm fairly pleased with the result.
