It seems since Digital took off, correcting vertical lines is like a fashion. I personally see nothing wrong with tilted buildings unless your aim is documentary. In the slide days only achitect photgraphers bothered with exact straight verticals using tilt-shift, very expensive, lenses. It is a beautiful striking shot, and the colour and design is well balanced. Since the image is pictorial in nature, I like as it is. With regard to the second image, to me, the oblique angles of the lines of the baskets-shelves combined with the bold colours give the image a dynamic quality.
