The typeface looks a little low quality - I think it's because the bevel you've placed on it has too much depth. Reduce the depth, and soften it up a bit more.
The glow and motion blur looks nice, simplistic, but nice.
Reduce the opacity of the drop shadow and soften it more - it's too dark/heavy at the moment.
You should begin to focus on more image-related signatures, as text based work leads to a dead end.
