So what you're saying is basically: "the example I prefer is really bad and doesn't match the image in most aspects, but you can't come up with anything better so I'll go withe that for now".
Now I agree that at some point you have to say "it's probably not gonna get any better than this" and tentatively accept your best guess. That doesn't count if your best guess is extremely bad though (see my list above for why I think so).
It's easy to produce better examples, even from life. It's got scales, a flat head, forked tail, relatively short legs, greenish color, curled up position. That seems rather reptilian to me. Here's just an example. This lizard is from South-Africa, so it won't be this exact species:
