Kickass, love the background and text, fits perfectly. My only complaint is the energy behind Ermac is too blurry, don't know if you meant for it to be that way or not but it'd look nicer if fixed.
Oh and to answer your question dragon no I don't have a bigger size. I could probably make a bigger one but I'm to lazy to do that haha, and I wanted it to be blurry otherwise it didn't look quite right at least to me.
