The pair of hammers(particularly) and the "Versus" doesn't look so good. The hammers look cartoony and overly polished and defined when compared to the fine detail and intricacy of the back-drop. The "Versus" is perhaps too large, I'd be interested to see it without the hammers or smaller and moved and/or faded/blended differently or not there at all.
The rest looks fantastic! The fonts(Versus aside) blend and sit really well. Imagery and theme/s are nicely integrated. Great colours and overall balance.
All my opinion, hope it's not offensive.
