I've also been following the development of this map in IG. It looks very impressive in it's whole size! Great job with the map and especially with the colouring. Somehow I've been thinking that you can't make a good map with coloured pencils but you prove it wrong!

Maybe one thing I could give critique is that the river looks a bit unnatural with its unchangeable width. But it's not a big thing really, I like the map a lot.
