I don't know how familiar you are with Mixed Martial Art's fighting, but I would be interested in seeing more detail on the logo, specifically, if the hand was shroud in a MMA style glove. I think this might put us on the road of designating that this specifically deals with MMA fighting.
I'm not sure how it would look...but I'm curious how the globe would look on the bicep instead of the shoulder?
Also, and I'm sorry if I'm being hypertechnical, but because of the positioning of the glove on the hand, it now looks like we are seeing the fighter from behind instead of from the front. I don't want to have anything on our logo that subjects us to any criticism or that any fan/critic may think is odd or weird, because the positioning of the hand just seems a bit odd.
Otherwise, I like the direction this logo is heading. Thank you for your hard work!
