Against what most have suggested here so far, I actually like #47 significantly more. Here's why: When I hear 'translator', I immediately think of someone furiously typing on a computer or transcribing something on paper - nerd-like behavior, which the glasses really do emphasize. Also, with #47, the face of the caterpillar is the main point of focus, with the rest of the body relatively undemanding of attention. That sort of emphasis and meaning isn't in #44, imo. And the type in #44 is too styled. You want something effortlessly readable.
