That's a lot of work you've done there and thanks for the animation. Most of all I like the terrain colours, which I have stolen to produce this sample. It's too bright and I've split the ramp into twenty-one colours, but this doesn't use them all.
Does this mean I'm an influential cartographer ?! I'm not ready for that sort of responsibility !
I wonder if I waste a lot of my time adding effects and details that noone will spot until they're pointed out ... was it Chippendale that was asked why he was polishing the top of a door that noone would know about, to which he replied "I'll know"? Something like that !
Your example ... looks a bit like mine ! It looks really good. For a long time my terrain looked a bit much and it was always the greens that let me down - too acidic or too bland - I find greens hard to get right. One thing I have picked up is I nealy always use multiply or overlay blending mores which intensify the colours and contrast so the underlying dtm doesn't have to be nearly as vibrant as you'd first think.
