It's fantastic. The mountains are amazing. I'm usually not a fan of caterpillars, but for some reason, I love these. As MCC says, it's very tempting to try the style. And I have to say, I'm impressed by the hand-drawn graticule; that is NOT easy!
Like yourself, I think the labeling needs more work. It feels too digital to me. How would it look if you just removed the dark glow and changed the text color to a dark grey? Maybe add a small noisy blur as well, to make it fit with the pencil lines better. I would add that to the city dots as well, and shrink them and lower their opacity, so they are not so strong against the softer original drawing. And lastly, am I correct that the paper is a texture you added digitally? If so, I think one that doesn't have the orange blobs would be better, they are a bit distracting in the otherwise monochrome drawing. I like that the paper is mainly grey though, rather than yellow-ish. Grey is underrated
