It takes exceptional talent and years of training to create a truly photorealistic artwork in traditional media.

With CGI and the right tools, it only takes a few minutes. and no artistic talent at all.

 

Of course you can't use a low-end hobbyist tool like Poser as a benchmark for what CGI is currently capeable of.

As for tangible artwork:

You can easily create limited edition 2D or 3D prints of your work if you need something your customers can hang on a wall or put on a shelf.
