Im on my work PC now and ive realised that the image is alot darker than i thought, ive been having calibration problems with my monitors recently, it might be time to buy a new one. Ill give all fo your suggestions a try, thanks for the help so far! Also in regards to the portals, Its very useful that they work with any light :D
Here is a brighter version of the image adjusted so it looks the same on my work pc as it did at home.
