I have made changes you requested. I am currently unable to upload new files as the designer in second has filed a complaint regarding the brass knuckles in the design. I pulled them from some designs done years ago the knuckles were removed from final design and I have had them in a file ever since and was unaware they were possibly stock art. I have recreated them and will load new versions when possible. Sorry for the trouble had no intention of using stock art in your design.
I have uploaded a version using the suggested font.
My designs have been move to not ranked status because of the logo court. Just FYI the site admin ruled that the design was not a stock image. I did go ahead and recreate the image to look different from the sticker file you had upload with the contest just to be safe.
Im still not crazy about the font if you have any other options you think might look good and I feel like the knuckles and the MMA is hard to see with that effect on them. Our #1 ranked logo has that 3D look and it makes it pop if you can incorporate that 3D look in any of your logos that would be great. I like the shape of the knuckles in #38 & 36 the best.
