i agree india should be filled up because it's spices and wealth are significant in the silk road thus is very important to the well being of the empireI think India is too much significant to be left blank around this time. This is because as be may be surely knowing that India was dominated by 4 main powers during this period the Vijayanagara Empire, the Bahamani Sultanate, the Delhi Sultanate and the Rajput States (who mostly united under external threats). The other middle powers (with significant power to prove a credible threat to those major powers) such as the Sultanate of Gujarat and the Sultanate of Malwa too cannot be ignored.
So my suggestion is that you should fill up India in your map. Also I think leaving out the East Indies would be improper.
