Modeling the Companion Cube, from Portal

Recently I have missed quite a few lessons at Uni due to personal problems, however I have been very kindly filled in by a group of friends in class (thank you very much!)
In the time I've been away, there's been some Maya workshop lessons in which I have been told that they are being taught how to model the companion cube. Although I know it would be much more handier to go to these workshops, as I explained earlier, a fair amount of problems have got in my way and therefore I am running behind on these lessons.
So with a scheduled day off in the timetable today, I decided to have a go at modeling the companion cube myself with some trusty help of reference pictures from Google. Admittedly, I have never played Portal before, so up until a few days ago, I had absolutely no idea what people were talking about!

Using features such as the UV Texture Editor, Hypershade, Photoshop, a few lights set up and a new camera placed, I managed to end up with this as my model:

My take on the Companion Cube - rendered using Mentalray in Maya.

Debating on whether to leave it there and carry on with other projects, or take it into Mudbox to add some bump and specular maps just for the fun of it.
