The second picture looks quite flash I agree but it also doesn't look like the hook kick I know, the first picture is more like it. We were taught to bend the knee more though hence the hook of the name. I have to say no kick I do can ever be described as flashy lmao! I wish! I can kick the 4 year olds to the head and that's it, if I do a hook kick to the thigh ( or liver can just manage that depending of the height of who I'm fighting) of my opponent though it's as good as a roundhouse, maybe better as my heel is harder. Kicking low though is good, less chance of them missing or getting caught.
I could see it being somewhat effective at the thigh level, with the full hook extension, but I am not in favor of any kick to the head level LOL mid-torso (solar plexus) is really as high as it ever needed with any kick IMHO...But yeah, I was taught to do it with the full hook as well, about a 90 degree bend at the knee...
