That attempt of a comparison is by the way a nice try, but only a nice try.
1) One can't properly compare a 3D model just by screenshots/photos. Different perspectives, different camera settings, different lighting, different everything basically. That Honoka's face seems a little bigger here or is differently proportioned can happen just because the perspective is slightly different.
See what changes perspective and lighting can make?
2) The model that they use in that indie game is obviously altered anyway. Pink hair, bigger bust etc. You can easily rip the Marie Rose/Honoka model from DOA5, alter it slightly and voila. It's not rocket science and not that much work. Modders do it all the time. So if one is pointing to slight differences that does in no way eliminate the possibility that these game developers ripped Marie Rose's or Honoka's model from DOA5.
