I like the strength portrayed in each of these logos, but I can't say that this is exactly what I want. Dealing only with the "World Superfight" name in each of these logos, if this were the logo that I choose, I would like the letters to be more complicated in the sense that I would like to do something along the lines of adding bolts on each point in each letter, almost where it appears that the face of each letter was bolted on.
Additionally, with regard to the sphere and the lightining bolts, in conjunction with the name, it almost gives the appearance that it is a cartoon logo, but doesn't yet encapsulate the essence of a mixed martial arts fight. We want to be taken seriously, and I'm just not sure either of these get us there yet.
Additionally, the text used for the website doesn't appear "aggressive" enough.
