Thank you all for your submissions and your work. As a first step, we went through them and declined most of the designs we didn't like / thought wouldn't work for us.
We have noticed a few recurring errors that we would love to exclude, by adding a few more explanations:
We want our logo to be clean and minimalistic - Rainbow Logos or Multiple color gradients are out of the question, the same goes with anything that has Bevel & Emboss.
The icon that comes with the logo needs to be simplistic and abstract, with as few details as possible, and it also must be recognizable if it's tiny (think favicons) and on a different background (think of the fact that it needs to work as a watermark in the corner of videos)
We've also seen many icons that resembled different things, like fishes, flags, symbols that resemble people in different circumstances, a lot of scissors (which we don't like).
A topic that appears in many of the logos is the reversed play button that resembles a K, which again doesn't look right (because it's reversed).
A similarity with large-name brands should also be avoided (we've seen logos similar to the Visual Studio logo, Nintendo Logo, an Old Uber Logo, Hipo logo, an Old Picassa Logo and even a few that resembled the old Kodak logo).
Thank you all, and we're looking forward to your next submissions!
