They look fab! You've messed with tilt-shift in the Buffon one. The lights in the first Watson one look just awesome while the text is not up to the mark. In the second Watson set, the lights are overdone and text doesn't suit. The Kohli one is just out of the planet, that text Woah! Some lights in the Buffon one could look good but all of the above shopwe that you are improving with every work you do.
