Recently I published my images from the Sagrada Familia here. The basilica itself is a piece of art. Further processing of the images might be unnecessary. However, when I ran some images through the Fractalius filter I was quite impressed that I thought it was worth to publish them too here. The first two below are images from the scale models.
The image below is made of the altar area, where in the ceiling the light from the Maria spire gets through.
And even the ceiling comes out nice.
And finally, the sculpture of Peter, mourning about betraying Jesus for the third time.
