Very realistic

OMG! that test is amazing (btw, all your work seems to be amazing!)

1 hour rendering time? I thought Octane was very fast because it uses the GPU?

The speed of Octane depends on many factors and settings. For instance, the choice of rendering kernel makes a huge difference. Octane comes with 3 of them and I'm using probably the slowest one of them all.
And yeah I have. GTX Titan and a GTX 780Ti and both were crunching at the render together. So, if it was just one card, it would take 2 hours.
Still the rendering speed was over 3M samples per second.
Also the output is very good usually after few minutes but I just let it run longer and to higher target sample values as the longer it runs the better the final quality is.
Usually my render target is between 30 - 50k s/px which Β translates into rendering times of around 8 hours.
If you use the DirectLight kernel in the Octane then the rendering speed is usually like 10 times faster and often even more than that. DL kernel however, has other drawbacks...

I still want to get it, probably next month but it does sound like I have a lot to learn! I'll only have the one titan card in my computer for the moment. I may get another one sometime next year or something, we'll see.
I know with Lux it worked the same way, basically the longer you let it 'bake' the better the render looked. Maybe I'll try to look around on their forums and such and take a look at these kernels.

Looking for information is never a bad idea!

Oh, man... losing all of that content is horrible - very sorry that happened.Β This is a lovely image, very realistic with the soft-focus background.Β The only things that jump out at me are the gloss on the lips and the reflection image (HDRI?) used on the eyes.Β The lower lip seems a bit too glossy relative to the exterior light implied by the background; and the eye reflection is crisp enough where I can make out a building on the right eye - also seems slightly off in context to the background.Β The fact that the image is so realistic that these points come to mind is really astonishing.Β Great, great stuff.

Yeah... lost all my custom created objects, materials, textures... In about two weeks and after I pay $600 for the work and $200 for a new drive I will receive all the data that can be recovered from the dead drive. Only then I will see if it is going to be a total loss, or whether anything can be salvaged... But back to the image...
The gloss is uniform on both top and bottom lip. To be honest, I wanted them to be this glossy, although it may actually be a bit unrealistic. The scene is lit by a HDRI map and the reflections come from the map. The HDRI map isΒ some factory ruin building with dense green nature but also dark shadowy areas around it so the reflections are actually spot on. The background is just part of the HDRI map as the scene contains just the figure and nothing else.

Interesting - wouldn't have guessed that was the source for the background.Β Well, it's darned impressive.Β Good luck with the data recovery.
