Been using the isometric style for a while now in my work, but by eye. Yes, isometric design BY EYE. It's really nice to have the guys at DKNG walk me through their process so I can make my work more accurate. Off to make a personal project now!
I will say, however, that while the monochromatic green palette looked great when creating the first few buildings, I found myself in situations where my palette didn't have enough reach (I know, he warned me at the beginning - my mistake). This caused colours to run together in a few sections (I'll point out, the shadow of the small left bush as it casts on the building's driveway).
