Samsung:
Lighting the space becomes more complex as more light sources are added, as they can add to each other and it becomes harder to determine which source is the cause of over brightness. You might want to turn on only the WindowLight and then only each of the General Lights to have a clearer idea of each's contribution to the scene.
Your perspective has changed between Rest..jpg and Res.6.jpg (the camera is further back) so it is harder to evaluate the different lighting solutions on the vault. Rest.3.jpg looks the most even (with the WindowLight), I have found this lamp easier to control than the General Light (which is more like a ball of light). If you have a light that works for a portion of the vault, you might be able to then copy it along the length of the vault. The General light might need to be moved down further so a smaller portion of its "sphere" of light is on the vault, so the light intensity values of this portion have a smaller range (this guessing that the General Lights are creating the uneven light from front to back seen in Rest.6.jpg).
All of this is part of the learning curve with LightWorks, what you figure out from this exercise will help you with subsequent renderings.
HTH.
