I like the 3rd from the top, my advice though, why make the render so small. Ignore how pictures are cropped, a sig is not the same as a picture and when cropping it the conventional wisdom of pictures can be thrown out. Don't be afraid to cut off fighters at unique places rather than making them to small.
