first of all: you are about to make me write my first critique ever, so this is a good thing
when i saw this deviation among all the others in my inbox i thought: wow, black and white, details, precision, i've got to see this in a large size.
i really love the very clear geometric shapes you chose. there's a big variety of patterns on the hills and the finer and thicker lines make the drawing more exciting to look at. must have been exhausting to draw them but it payed off. i also like the contrast between round and edgy shapes.
it looks like you worked really precisely and i think to draw trees and hills in this way is quite original!
