Hello and thanks for your comment.
While I initially planned to keep using sprites for misc things, I now have recreated everything (save for the characters) in 3D, including tiny stuff like the ink pot on the desk. It avoids IP infringement and is more compativle with the 3D world, allowing for camera angles etc.
I'm 90% done recreating the world from the first act of the game (up to Jake's exile in the Car Yard), and that is done, I will try to create some low poly characters (more low poly than the ones from Shadowrun Returns) based on the SNES sprites.
So, keep tuned, the coming weeks will hopefully see some renders or even a playable demo (I've been programming in Unity for a few years now).
