Well, here it is, the official reference for G'lek.
I've spent many years designing this character, and in more than the visual sense.
I plan to post something sooner or later that outlines his species, called the Ta'rall. For now, enjoy the art.
Art belongs to Royalty (https://www.weasyl.com/~royalty).
G'lek belongs to me, do not use him without permission.
