Oh yeah, comic artists are constantly ripping each other off. As to whether this particular artist took inspiration from the Flash or Quicksilver or Superman or any other super-fast running comic character... who knows.

On another note, I really like the look of Blurr in this comic. Very Hermes-esque (as was Golden Age Flash now that I think of it, heh - so I guess that strengthens jacksplatt11's theory ).
