Further Development of 3D Model

 First I removed the cube on the top to give space for the light, then I used the bridge tool to cover the hole of the polygon therefore the light would have something to sit on.

Here is a wide shot of the 3D model.

 I then created the light for my lighthouse by using the designs in my concept art. I created half of the image and then used the mirror tool to make it symmetrical.

Once I put the light in place I used a new blinn to give the light a glass style for the light to pass through.

 I then added a few colours just to help separate the sections of the model, I also grouped parts of the model in the outliners window.
