Well, there's the UMD store to get you started. Don't recognise that particular shoot, though. Perhaps you could check if there's still an external site too, or contact the producer directly. I know there would sometimes be a long gap between shooting and posting with that site, and I've a feeling pictures might exist of shoots that are still stuck on the owner's hard drive and never got as far as the public. Also, that producer hasn't been regularly active for some years now. (Their heyday was about 2010/11.)
This producer has a habit of teasing us with some incredible preview photos, then never gets around to releasing them. They are still semi-active on Twitter, but they still seem to be talking up shoots they did years ago which haven't been released.
The stuff they have released has been excellent. It breaks my heart to think of these amazing shoots just archived on a hard drive somewhere, possibly never seeing the light of day.
If I recall, the producer was hesitant to release this schoolgirl shoot because he was worried how she looks underage, despite her being in her 20s I think. Would be great to hear the producer's input on this, and hopefully some updates on the other shoots he has yet to release.
I was wondering if I was being a bit harsh (or my memory was awry) by implying that pictures of a shoot from this guy do not necessarily mean the shoot itself is available, so I'm glad it's not just me...
