That looks pretty good for a first effort Can't really give you any advice but keep going and you'll be good
Thats a pretty good sig for your first try. Just with the logo put the opacity down a touch so it blends with the bg. The player effects are pretty good too. Keep at it, and youll get heaps better.
Nice first attempt.. Hate the background though and dont like the blue on the text also the render should be blended with effects but its only your first time also the badge should be blended or have effects ... use some tutorials..
