Midterm--Pirate's Cave

Still trying to get the damn thing to render. Here are my attempts so far, just to show you that I've been working on it all night. And will still be working on it :(  I keep changing the settings, the lighting and it's still not going all the way through the rendering process, even at a low setting.

Pirate's Cave

For some reason maya isn't rendering in mental ray and I'm not sure why. So here is a screen grab so you can see that i've worked on my  models.

Hopefully you can help me figure out why it worked last night but not tonight. :(  I'll also post some from last night. do you think it's because I brought the zbrush low poly version of the caves in?

Off the coast of Fiji, where the natives grow restless. They lay wait for any pirates who try to find their hidden cove of treasure.  Pirates travel from far off lands trying to find the hidden treasure, however,  they will find more than they bargain for. The natives imprison their captives and steal their booty, and pile it on top of the heap.  The Pirates are shackled and imprisoned and forced to look at their precious treasure without the ability to obtain it. They will die in their coveted cave.
