Thanks for the responses!

I saved it as bmp and converted to jpg. I had my render quality at intermediate. I increased it to production. Also, I'm using maya software renderer instead of mental ray on this one, so I'm sure it would be better quality had I set it up for mental ray. I'm not using any raytracing in this render either, just depth map shadows. I'll probably mess around with trying some other settings so I can see what kind of results I get.

I still need to fix up where the floor and wall meet, thanks for pointing that out!

Here's a new image with production quality render.
