Here is a worship center I just completed. If you were reading the “lots of chairs” post, this is it. I will probably revisit this one when I have time.

Worship Center
Update.. Any suggestions would be appreciated.
Here is the lobby of the same project
Hmm nice done. but overall i could be a bit more lighter. seems to dark.
nice work, i agree on the darkness/blueness though, and maybe your carpet is a little too grassy?
a little more contact shadows on your people and less bloom would be nice in my opinion
nice images… i agree with the comments…
as well… look at the carpet underneath the new hope sign on the second image… looks like you need more segments…

Interiors
I have been having the hardest time with interiors and IES. Sometimes they work and sometimes they don’t… all in the same file. I can stop the render, tweak something, start it back up and then the lights will not work. I have to delete all the lights and add them back in. I also had the same issue with the sun. Sometimes the sun would shine through the windows and sometimes the light wouldn’t.
Here is an update on the Worship Center. I fixed a couple things and replaced the seatings. Although they will not have folding chairs the stadium seating I had made the render take days instead of hours with these chairs.
I am also working on the blue lobby and will repost later.
Re: Interiors
It might be a lot faster to tweak the brightness of the image in Photoshop. Hope you don´t mind but as an example i adjusted two of your images.
I used less than a minute an you can do it all by adjustment layers so it will be easy to keep the settings if you have to re render again.
I like the way you put in your logo in the lobby image

The sanctuary really popped, but it got really dirty. I’ll try some photoshop stuff. I have a photo of a similar sanctuary and it is dark so I tried to match it. I’ll post the photo to compare.
