This is a definite example of true talent...
That once you master something, such as Photoshop, Even something as short of time as 8 hours can produce a masterpiece!
Something like this would probably take me a whole year to do by hand.
(Using actual paints and stuff)
So it's kinda an "Awe" and and "Ah" for the point of view of artist.
For one...Mastering Photoshop isn't easy.
On another...Photoshop kinda depreciates the value of fine art that originally took months to do by canvas.
For example: No one really does oil-paintings anymore. Art like that could look just as spectacular as this...but would take months to make.
Photoshop and Technology in general could very well make a picture like this done worth less unless it was done using actual oil paints.
Although I suppose that in the prime example of perspective, one can see that this artist from Indonesia has taken the possibilities of Photoshop to an almost unattainable level of talent.
It's Good...because you use Photoshop to it's full potential in such short time invested.
