No offense but this banner needs some work.
Well, here are some things I have to say.
1. Never ever lower the render's opacity, it doesn't help at all.
2. Sharpen the render instead of the background. When you look at your tag, where do your eyes go first? To the render or to the background? Try it. When I look at your tag, my eyes seem to go to the background first.
3. Stay away from text. Learn typography first. Make sure the render sticks out more than the text. I myself, do not put text very often.
I suggest reading this tutorial. It's a great beginner tutorial. Try to study signatures that you find nice, that's pretty much what I did.
Download signature PSDs too.
