Add a 1, 2, or 3 pixel border, the pictures don't blend properly, and when using render you should cut it out and overlap it with the picture that has a backround so it isnt just a plain white background.
Also the font should be smaller and more off to the side. The fighter should be the focal point not the text. Which in this case the text is.
Check out this video for the fade effect:
And check out this tutorial from out very own Toxic:
It explains how to cut out fighters to use them as renders. Its basically just the pen tool but he explains it perfectly.
Please do not take what I said in a bad way, I am just trying to be constructive. You will get better with practice. Remember that in photoshop pressing F1 brings up the help menu, search anything you want and it gives you a fairly good answer and usually a quick walkthrough.
Best of luck in the future and if you need anything please ask
