It isn't very good, but I did only take a few hours on it. Got bored and here you go. 

still looks better than mine!  mine was just a war doctor with coral roundels

 Best Coral T.A.R.D.I.S I've seen in my life.

Good, but I can make some adjustments:

You'd do better with a combination of Coral Wall, Coral Wall Divider and RoundThing_C 10 than 10Doc_Wall

I like the detail, but there's only two levels, the bottom hexagon and the top circle, and there's no ramp between

The pillars in the front and back should be facing directly at the wall instead of sideways like that

It should be noted that there is a proper walkway going from one of the front pillars to its friend on the back, and the same for the other side. If that makes sense.

The top circle is a bit smaller than that.

There's a whole bunch of lights and wires and such visible under the floor in the actual set

The upside-down cone on the ceiling is bigger, goes to the ceiling and is sandstone-coloured

There's two railings up top, one on either side of the console. Left and Right, with respect to the door.

This is one that most people miss, there's two bits sticking out on either side of the door. Basically surround the door in Granite (the DM kind) and replace the top 3

And the visible Toyota under the console kinda mucks up the immersion.

I love the overall design! :)
