Yes, I was always fond of Stonemason's work, but he's gone DS only the past few years, so I don't get any of them any more.
You're lucky he included the OBJ, because I've found most PAs at DAZ who create for the latest versions of DS, don't include the OBJ, because it's no longer needed, otherwise I'd do what you did, and wait for a sale, and then use the OBJ. Of course that means manually installing the appropriate textures, but hey, I'm an old hand at that.
Anyway, this is looking good so far. You'll need to work on the lighting some, as the girl is in so much darkness, you can hardly make out she's standing there. Otherwise, it looks like a nice set.
