I appreciate your doubts, but the pictures are quite real, the fact that my pencil strokes are similar is simply technique. A straight line is a straight line, a brushstroke a brushstroke. In reality the paintings are not particularly photorealistic, if you want to see a really good photorealistic effect view Photorrealitic bulb. Not everything needs to be done by computer. I do indeed have a copy of Corel Painter, and where used I pointed it out. I also have a program for preparing photographs called Zoner Photo Studio. As for accuracy of drawing, that again is a matter of technique and practice.
