Many thanks to @midoken for filling this. Now that I had the privilege to test both Shinteo and this version, I can safely say that this is not a "stolen" copy of Shinteo's work. The skin and body is totally different than Shinteo, I even compared it to small details like moles and the genitalia. It is not the same model. The skin here is way better and cleaner imho.
A quick comparison for all 3 Judy versions:
