grand canyon main problem is to showcase the depth, it cannot be seen clearly here due to limited size but i think the shadows will be more than sufficient to help with that. the only real quibble i have here is wrt the blowouts - you used gnd and didn't push it down enough?
pssttt... america got so many nice national parks, please visit monument valley :heart:
