I think I have to agree with Vik for now. Seems like it could be the western shores, with the northern edge of Vylbrand/O'ghomoro coming in at bottom with the Strait separating it from the mainland, with the Indigo Deep as the central focus. Could be a small glimpse of the New World to the left as well. The smaller islands, I'd say hard to peg whether those are actual oceanic islands or sky islands, given that we know sky content is coming.
