Wow, this is great, and the improvement between this and your first map is impressive. I must say that I agree with Pixie re: the geology, though of course it's up to you if you want to redo it when you've gone this far. Though your mountains are far better, it still looks rather jarring to have it as essentially one cordillera with branches, rather than several parallel or unconnected ranges like you'll see in the Andes, the Rocky Mountains, or, well, kind of any high mountain range. Especially so when the style itself that you have is so beautiful and realistic-looking. Your larger rivers also look a little... odd... to me, especially the main channel of the river with its mouth to the southwest of the Mokhaṇṇam Mountains. Rivers are hardly ever that straight and/or angular, unless they're almost wholly manmade. I'd redraw it a bit and add some more curves and meanders to make it look more realistic.

I'm also a huge fan of your labeling- I like seeing some diversity of languages, and the extra letters. My limited knowledge of the IPA helps with some things, but I'm curious how you pronounce that ħ though- is it a voiceless pharyngeal fricative as my PhD in Wikipedia tells me?

Anyway, this is great work, and I'll be watching this one!
