The artwork on The Flash #19 is a little more erratic than usual. Both Jesus Merino and Carmine Di Giandomenico are great artists yet they have decidedly different styles and strengths and the way the workload is split in the story is curiously conflicted. One oddity is that Carmine Di Giandomenico - whose strength lies in kinetic action sequences - handles the quieter section near the end of the book, where Barry and Wally have a long overdue talk. The sequence works, however, despite seemingly not playing to the regular artist's strengths. It should also be noted that the colors by Chris Sotomayor are fantastic throughout.
Whatever conflicts exist in the art are not born of the story. Joshua Williamson's work is as fine as ever and he writes a wonderful Digger Harkness here - every bit the professional and sleazeball, yet with enough of a soft-side to inspire a modicum of sympathy. The closing scenes between Barry and Wally, however, may have you reaching for your tissues.
