Looking good as usual. I don't have an issue with extending parts past the neatline - I've done it myself in the past, and as you said, it IS an established practice, so it's not like you're breaking down the very barriers of reality!!!!!

As far as that island on the Hareshk map - the placement of it now makes it appear as though the land in the southeast corner of the map is an isthmus. What about moving the inset map up above the cartouche?
