While I take your point re grasses and that will surely change over time either for the good or the better depending on how they manage it, what jumps out at me is the small conical "dunes" in the off fairway areas. From a distance and all together they look un-natural and indeed shite.
Not that un-natural features on a course necessarily look bad. Most greens, bunkers and nearly all tees look un-natural. That can actually work well where you have some bold shaping or indeed a few straight edges. However I think the trick to that is setting these un-natural features in a natural looking setting. In the context of Dumbarnie, the conical dunes are meant to provide the natural setting and to my eye they fail to do that. That said, the playing areas themselves looking interesting and well worth a play but not just yet.
