Hi Luke,
First of all thank you for this great job.
Among your 6 propositions the #4 is my favorite one because the letter "Y" is well/clearly represented.
However, if you are ok, could you try new versions with:
- the left "Y" with more depth/volume (but still straight)
- write Yakaferci in two different colors (yaka AND ferci)
Thanks for your help.
