thank you for the submissions!
#4 - i love the font you used for "digital" - it's understated but powerful. i really like where you've gone with this design. the "423" is just a little difficult to read.
#3 - i do like the perspective angle for the "423" but i prefer the way "digital" is not angled like in #4. overall, it does have a cool, star-wars-like feel.
Regarding both #3 and #4 - i totally dig the black background...from a practical perspective, i could see some instances where it would be put against a different background, e.g. someone needs the logo for a step and repeat with a white background. that said, i just want to make sure the design is versatile across multiple backgrounds (including and especially black!)
