Hi Arena, thanks for your submissions! (#45, #46, #47, #49)
The idea behind the icon in #45 and #46 is an interesting one: We like how the Q icon has a complex structure, how there is judicious usage of 3D effects, and how the little tail in the "Q" goes from back to front, giving the icon a perceivable depth. It works much better on black (#45) than on white so maybe you could make the logo stand out better in #46.
What we don't like about these logos is the text. The font you picked in #45, #46, and #49 is too classic and not modern enough. Take a look at our top-rated logos to see the sort of font we prefer. Also, quantumcode is one word, and it does not look good when you split up the "quantum" and "code" and make them different sizes. Instead, could you please add our slogan ("No Uncertainty")? That would look fine in a smaller size.
As for the icons in #47 and #49, neither of them is particularly striking. #47 is too complex and doesn't immediately lend itself to interpretation. #49, while we appreciate the idea behind it, is too "classic-looking" and also too symmetric. We are looking for something really modern and uniquely recognizable.
We are currently trying to get designers to try other ideas besides just stylizing the letter Q. We really hope to see some more ideas and refinements from you. Thank you!
