This is a nice and simple logo with a good color scheme. The font choice is decent, although the boldness of "Quantum" and the thinness of "code" do not work well together. We also seem to currently be preferring all-caps text right now.
Could you please add our slogan? ("No Uncertainty")
The idea of a leaf as part of the sphere is initially appealing. We're still not sure if that's the direction we want to go, as we are not necessarily trying to emphasize a "green" initiative from our company, but it does look nice. The gradient / lighting on the gray sphere is a little dim and lackluster, and the overall shape itself is a little plain and lacks any subtle details.
You have a nice style here, however, so we really hope you apply it in your updates. We look forward to seeing what you can do. Thanks!
There is less than a day left in the contest, and we are looking for some new ideas here. Please submit anything you can think of, and we'll work with you to flesh it out if an idea is promising. Looking forward to it. Thanks!
We really need something more sophisticated, refined, and photorealistic than these ideas. If you have any, please submit them in the last few hours. Otherwise, thank you for participating, and good luck!
