Boo! 
Right before your door, you have a couple of parts overlapping, causing a ‘glitching’ effect.
Multiple areas are either really bright or really dark. I presume that you are using blocks that are invisible for the lighting. Remove all of those and go to your Explorer. Scroll down to Lighting and change the Ambient to a lighter color or just make the black a gray or white color:
More overlapping parts here.
Empty and wasted space here. Move the mannequins against the walls, and then, add some decorations.
All of the mannequins here face in one way. It looks like a scene from a SCF game. I would suggest 1, spreading them out and 2, rotate them.
Way too much going on. You really only need one (1) pattern per room.
More overlapping parts.
More overlapping parts.
Continue this pattern throughout the deck.
More overlapping parts and continue this pattern throughout the pathway.
Please, stay away from free models with viruses. When I first joined the game, it tried to teleport me to another game. If you do wish to use these free models, use an anti-virus plugin to get rid of the viruses or check the scripts yourself.
Everything stated here in this post is merely based upon my opinion and my first looks. Please, do not feel disheartened or feel like you should follow everything I have stated. This is just feedback and meant to help your building skills.
Also, you have a bunch of neon parts in your game. It can be an eye-sore, especially at night or early in the morning.
Sincerely,
