Environment Lighting

These past few weeks i have been finishing texturing my environment, adding some detail to the parts of it that are visible, and adding some character with some wall displays. On top of that, i have been lighting my textured environment, and have reached a render that looks quite nice:

This is using a bunch of different lightings and some global illumination and final gather settings. The drawers on the right are not really seen in many of the shots, so their texturing is very basic.

I have also rigged all of my characters to an acceptable standard, and they are now ready to animate! Unfortunately, some problems have arised with the lighting that i'm using causing unacceptable artifacts on the skin shader of my characters, as seen below:

I'm currently seeking advice from the internet, and may ask some tutors at some point, although none of them work in my program, so are unlikely to be able to solve this specific issue.

I'm also taking stock today, taking the amount of time i have remaining into account and editing my animatic. I'm going to refine and finalise all my camera shots, maybe take a few out if i can. At present, i am confident i can finish in time, with my biggest worry being the rendering. If nothing else goes wrong with the renderer this shouldn't be too much of an issue, but i have just upgraded my PC to be sure, and now have access to two high powered rigs to run off my renders.
