No, the markings in the original link image are drawn from scratch, there's no resemblance in their form besides a general line-width and color. They're pretty clearly just scribbles.

Edit: Since people are getting up in arms about this despite having no idea how markings work, and these seriously being obvious scribbles, let me explain to you how patterns are generated, biologically, and what I mean by "form". It was late, and this takes some time to explain.

The way you get random patterns of color is not truly random; it's due to gradients of hormones. Here's a solid (and relatively comprehensible) article on how this happens in mice.

This is not trivial; it's not just a matter of "oh, this part should be purple and this should be black, and just, uh, genetics!" It happens by a specific mechanism. Effectively, each of those patches of color is due to a cluster of cells that is generating a signaling molecule. As the levels of that molecule drop off moving away from that cluster, the cells that have coloration in the skin respond; in this case, for example, they generate a purple color when the signaling molecule is at concentrations between, say, 70% and 40% of maximum. When signaling molecules drop off to near zero, at a sufficient distance from another cluster, this allows new clusters of cells to begin generating the molecule. (There is also active inhibition happening, with the gradient going from 100% of one chemical to 100% of an active inhibitor, but this has the same practical result). Same principle happens for everything that has color patterns.

You know who figured out how all this signaling and inhibition worked? Alan fucking Turing.

SO: My problem with the illustration (which is what it is) is that it has no "center-out" form like you would expect based on how damn near everything generates color patterns. It's random scribbles, when that is not how spots and stripes are biologically generated. Compare the pattern complexity (how many times it switches from purple to black and vice versa) in the actual animal versus the illustration: The illustration is inconsistent, has vastly more switching, and has no center-out organization.
