Sad to say I am not gonna pull any punches here being somewhat of a professional of photoshop.

As Zenrgy mentioned your image is too cluttered; I can already tell that you wanted the war to be the focus since you did not make him blue and faded him in the background, but keeping all your other characters at 100% opacity stole the focus from him the moment you set eyes on the image. The screencaps themselves are poorly cropped, the remnants of the background give the overall project an unprofessional look; Also the screencaps (or the image altogether) is pretty low quality causing multiple sattelite pixels to appear, making the image look bad. The background you used/made (cant say for sure) is really good, but you never should've distorted the area behind the blue characters because once again it steals the focus from your warrior and also disrupts the general flow of the image.

There is a way to make this wallpaper work, but you have to work alot more than an hour and have some knowledge in the mechanics of the pen tool. If you use the pen tool to crop your screenshots you won't have all the background trash that destroys the wallpaper. If you want to keep all the characters in there and still make the warrior the focus then I highly recommend keeping all the characters in a organized fashion with an opacity of 30% and overlay the blue color on them with either an Overlay or Soft Light blend mode. And finally, above all else, try to keep the quality of the image as high as possible to where you can upload it to your imagehost. Quality of the image is the key between well done and cluttered with trashy pixels.

Hope this critique helped you in any way.
