I look on it this way.. if someone is painting you wouldn't reject the painting because the brush strokes are visible. So why is it a problem if pixelation (which is an inherent characteristic of digital art work) is visible or deliberately incorporated ? I want my images to have unplanned elements and rough edges I wonder if in 100 years from now.. the ever more detailed and clean digital photographic images will be of any more interest than the old grainy black and white photos of the pre-digital era ? Personally I doubt it. If a printer/client/photographer is going to judge my work by photographic standards my work is always going to fail.
For me the above detail has lots of interesting contrasts and nuances going on..I'm not ashamed of the fact that I am using the digital medium.
Constructive comments welcome
