Well archVis is only one small element under the visual media umbrella and is generally a word to describe the genre that limits it’s scope to purpose and need of the client or individual. It’s a shallow market for such skills as to what’s realism verse realistic as compared to the market place (massive) where the need is for visuals that are interesting, pull focus, and the majority will accept processed visual as being real than a photograph as that is how the industry has taught them to think.
All things targeted under the mass market place is “always” posted process to make the imagery more interesting, to catch your attention, even though such images reject the ideals of single point lighting typical of archVis and favors the techniques used in film, stage, and even magazines that goes beyond the boring of pointing a camera at a subject and going click.
So as a frame of mind there is the question. Why would anyone hire you as a 3d graphics artist if you can only produce imagery that is equal to stepping outside with a camera and it’s scope is limited to a select few individuals?
Sounds confusing hu? 
Well to sell my frame of mind Eric Curry is one of many individual who inspires me as to the ideals I want to achieve in 3D imagery.
If you can pull of hyper imagery in 3D space then your sills would be in demand in all markets where the result “has” to be more than something that can not be captured with a camera and stepping out side.
P.S. check out his other videos as well as anything involving the painting with light technique as it’s use can translate to 3D space.
Just saying.
