First of all, thank you very much for your updates!
We want to give you a general feedback of the top 5 logos in our ranking, so you can get an idea of what kind of logo we want.
We currently think No. 1 (#511) and No. 3 (#573) and close to what we're looking for, because it is simple yet have originality, but we want a little more uniqueness (like "c" like No.5 (#712)).
We also think the balance of fonts/letters on No. 2 (#671) is good too. Maybe the balance looks good because the "C" is big and "es" is small, so looks balanced. *That doesn't necessarily mean we want to "c" to be capitalized. We just want the word "couples" or "Couples" to look well balanced.
Overall, the font maybe little too rounded, so maybe it can be a little more square-ish, like the logo of Vine and Path.
We want our logo to have: 1. Playfulness in the first letter "c" or "C", but the remaining letters "ouples" to be simple (like Vine and Path). 2. The font for the word "couples" or "Couples" to be well-balanced. Since the "couples/Couples" are longer than Vine or Path, you may have to adjust the size a little. Like make "c/C" a little bigger and make "es" a little smaller, and make the whole logo well-balanced.
