I don't have any knowledge in Turkish, but arkasında and arkadaşımare sound generally very similar to me. Maybe that is because the word for "friend" is a derivative of a more graphically origin, as in “the one having/watching my back”, or “the one behind me” in both a literal and metaphorical sense. It’s in any case a fascinating observation.
My fascination with languages aside, it’s a really beautiful comic strip. I love how you do the details, shadows and textures, not to mention the way you make them seem alive and caught mid motion.
