Continuing lighting experiment

So i have been continuing with the lighting experiments and just recently have decided to download a pre - rigged model and put it in the scene. The reason for this is because i want to see how a potential character may look within the lights i am placing around in the scene.

I had to change up the lights and put in more different variety of lights because the area light was starting to become quite limited. I wasn't getting the right look. The rendered shots always seem to become too bright or too dark.

So i decided to put in a volume light and increase the size of it. The reason for doing that is because the light is being projected inside the volume light and so in order for it to have more of a significant effect in the scene i need to expand it outwards. As for the area lights, i still kept them in the scene but i also increased the size of the area lights and cut it down to 5 lights.

The results are getting better but its still doesn't look quite right to me and i am getting frustrated because all the tinkering and adjusting sometimes feels like it makes it look worse but i'm going to find a solution. The character within the scene also looks over lighted and shadows for some reason look really rough and jagged.

I don't know why the shadows of the character looks a little rough so i need to look into that.
