Hi & thanks for the compliment on the pleasing image :D
sincerely i can't see what others see in it, but as it brings cash and makes others happy i accept it as such.
It's just an example from Cycles used in commercial work. Simple bump map ;) and a good lighting did the trick for the designer's eye.
For me it's merely model-texture-composite & painting with light & shadow, finding the balance between time, client's wishes and my ego. Which is hard to satisfy, for it 'everything sucks!' Why i also don't show my works.
About Corona SA... would like to use it more, even commercially, but in state it is now, for me is not efficient... also has couple of showstoppers preventing bugfree production. So i help testing, providing feedback to the single volunteer developer when i can. Without motivational perseverance that blanchg (Glen) shows and hope that Joel gave when he started, this would be just lying dead.
Was also thinking about project based written tutorial... but too many times i hit the wall or some hurdle. Which i hate, as am not a competitor, but a visitor who wants to enjoy and share. The above image is part of the scene i wanted (already started) to translate & share the process of... from old house photos (elders moved on) through envisioning a bright future for the young family moving in. ;)
BTW
I also have a Maxwell3 license, worked with VRay most of the time, but clients have changed. They demand more complexity (realism), have less time and are getting worse at communication, constructing, providing their vision. So it's basically Cycles (fast iterations) to the rescue.
Finally, it's getting hard to give life to something that starts sucking & draining it out. Like a stale water. Unless it's always flowing, it stays fresh, otherwise (stale) becomes poisoning as bacteria/bugs take over.
