The drawing below is my small pixel art drawing!
Step 1: Learn the rule!
Make sure you use the pencil tool if your wondering and zoomed in to %1600
Step 2: Duplicate and Link
Step 3: Color your plot of land!
Step 4: Add dirt below the land
Ok so now lets add some dirt :D
Do the same thing below the land but make it only like 8 pixels lower.
Making your land larger is easy too. Just duplicate the layers, arrange them in a square, and merge them (cntrl + e)
Step 5: Use your imagination!
And one more important thing to know is making windows follow the rule but be sure to add a reflection to make it look better. I zoomed in on my picture so you can see easier
