Lovely app Rex! Cannot wait to see where this goes! Two notes for you, because I'm silly like that, the east coast of the hook would be a high-energy coastline, so the beaches would be rocky, and quite small, as the rate of sediment deposition is lower than the rate of erosion. On the western beaches, however, wave action is significantly lower, and so sandier wider beaches would form there. However, on the western coast, there is no onshore wind, so I'd argue that sand dunes would not fit there either. Wide expansive sandy beaches should be fine though.
Second point, I'd put more fortified structures on the eastern coast seeing as there's a threat of Essosi pirates and Stormland smugglers from that side, as opposed to on the east. There's also a pretty large holdfast on the western coast of Stonedance, which would probably be the port of call for anything on that side. You don't necessarily need to get rid of the fortification on the western coast, maybe just downsize it, as it would probably not see too much action, and would just be a precaution.
Best of luck, you got this!
