The reason i put the tiles in was because it looked too plain compared with the rest of the scene…i never seen holes for keys or barcodes on ceiling wtf so eeerrr wat lol? Maybe markings buuuut. eeh What about if i made them uniform?, but then the floor is uniform…might not look good either.
As for bevel i do have it! Check the post in the focused critique for comparison. 
As for the door, i guess your right but eh, lol, anything can happen? i might change it laterz.
About the green light on the keypad point…
This was actually discussed in the WIP threa, so ill give a summary here: I wanted to to both with and without a person scene, however i dont have a person model…
So, for this scene it could be interpreted as either someone alredy walked in and the dooe is about to close, OR someone is just opening the door from the inside, which imo adds a sense of anxiety, basically what you said, " it leaves me as a viewer thinking that this is a still from a longer scene, a still taken before something was about to get interesting." so imo it is a good thing because the image is basically teasing the viewer. Maybe that is not the case but that is my opinion about it.
Back to the person…i was thinking of having a guy in a lab coat in front of the door, when i deside to model him.
As for the script, i actually tried it, but it doesnt go too well with my scene because of the effects i am using in the compositor, more specifically the blur nodes. they blur all around to make a sort of halo so if the render is split into two you see 2 halos and id doesnt look to well (I already tried it actually
)
As a final note, i thank you for taking a deeper look into my render, it is always appreciated!
