I've been trying to get better at drawing environments lately, and one thing I'm struggling with is making landscapes feel less generic. I can copy a photo reasonably well, but when I try to invent a landscape myself, everything starts looking like the same hills, rocks and random shapes. I'm starting to think I need to pay more attention to how real terrain is actually formed. I've been looking at geological maps and landscape references recently, and it's pretty interesting how much information you can get from the shape of the terrain alone. It also made me think about how useful geological mapping could be for environment artists who want their scenes to feel more believable. Do any of you use geological maps, satellite images or other real world terrain references when designing environments? If so, how do you turn that information into something useful for a drawing without just copying the reference?
