Agreed with commentator above, at this stage everything is fine but the room proportions. It's became noticeable while looking at the main table in the center. On original concept this table feels smaller. I also think that metal barrels at the end of the room could be a bit wider. Good luck with your environment!
One thing the concept doesn't cover is the opening in the roof which is in most Frankenstein stories. Don't know if you want to put that in or not. Looking cool so far.
