There's a reason CGI is used for monster movies. The risk of being eaten by a 'coworker' was a little too high.
I rendered this as a test to see how Octane handled large images. I actually didn't notice much of a difference in render times even as the image resolution became larger. This one probably took 45 minutes and its resolution is 3840 x 3840.
I will be adding Octane as an option for commissions. If you have an idea that you want rendered, let me know.
