...still searching for the right words... impressive, for sure one of it but there must be others...
Like the colurs you used. Amazing count of details for the interior.
IMO you've done a great job with the corner section, though I have to say that I'm not a great fan of the top part. I guess very usefull for all the scientific instruments but for me it doesn't really fit into the picture, Some kind of cupola would give a smoother touch.
But anyway, AMAZING job!
