I have Poser as well, but I'm not doing the main render there - the app I use doesn't render in alpha channel, I'll fix those edges, though.

I'll probably have to shrink those statues a bit and move above the walls, on left of altar.

The line on the octopus tile, however is not a seam, but an actual dark streak at the center of the green marble, so that's not an error.

Small tweaks to fix these, thanks for noticing, RP.
