It's getting better, but there's still a few problems:
- The dark purple to black gradient makes the logo really hard to see with the carbon fiber background
- Poor font choice for bottom text; try using something less flashy, y'know? A simple wallpaper needs a simple font.
The logo itself doesn't really go for what you're aiming for exactly, but it's still nice.
Reduce the brightness on the white border, and/or fade the opacity a tad, it's a bit straining on the eyes.
Get rid of the reflection on 'Design', it stretches the focal point too far vertically and takes away from the focus on the logo.
Not sure if it's intentional, but the cutout behind the fancy S is sorta shoddy and looks unprofessional.
If you're looking for a 3D look, you're going to want the background to come over the edge of the S, and not the other way around.
Looks like it says 3G. Do you want to be taken seriously with the whole graphics design thing? Because the whole futuristic design logo really only applies to Youtube, montage clans and shit like that. Outside of that world it looks really immature. Don't mean to cause any offence, but that's how I see it.
