That was horrible advice...
He made an abstract sig, doesn't necessarily have to have blending, and it would like kinda bad if it did. Not everything needs to have a render or a stock. Depending on what you make, somethings look nice without it. And never, ever, encourage people to add text. This is probably the hardest part in tag making, and it is really hard to choose a good font, size, positioning and colour.
On Topic:
Not bad, the texts you have added look a littler weird, especially the one in the glowing line. Try a smaller canvas size. I can already see from this that you were trying to add stuff to fill in space, which is never good. Maybe try 350X150, and smaller.
