Looks cool, you've certainly improved it a fair bit. Can I suggest you add a bit of detail to the background? It just seems a little bare. Also maybe some DOF so the hoses close to camera are blurred.

Yeah its not finished or anything. It was mostly for practise volumetric lighting. Theres meant to be spotlights all around the tank, so you wouldn't have that blandness behind there, but I didn't get around to it. Also for some reason my lights didn't render.

I put self illuminating spheres at the origins of the spotties so it would look like they were shining lights, but they didn't render.

Did you try using the Vray light material?

I think I did... must have been a reason why I didn't use em. Might try them again.
