WKF - logo, icon, logotype, branding

Tonight i'm interested in redesigning the WKF (World Karate Federation) logo, my version. Trying to make it look more modern without leaving its identity, and can be applied to various media. What do you think?

By the way, a few days ago i uploaded a video about the process of redesigning NASA worm logotype on my YouTube channel: https://www.youtube.com/watch?v=o1WgBX17z4I
