Hey ake,
Awesome work!
Okay, #14 is a favourite along with its counterparts, #13 and #15. Very clever with the G and the helmet, just noticed that. Perhaps a version of them in black and white and a little more refined, not as thick. I like the type face, but maybe one slightly different just to see, with slightly more flair.
For #16, #17 and #18 - Love the idea of the swords, and the G as a shield I believe you are going for? But the G doesn't look quite right, perhaps an actual shield with the G on it, and more of a sketch look and a different type face, that one doesn't suit 100%.
Thank you, great work!
