First of all, congratulation! You are currently No. 1 in our list! We are like the shape of the font on #648!
If possible, we would like to see different version of icon! We like the font of the logo, but we would like to see different icon. It would be great if you can give us an icon other than 2 hearts tied together!
And it would be great if you can adjust the shape of the font a little! We would like to more variation of the shape of the font used in the logo ;)! It would be great if you can make the font look more mature, so it will fit our users taste.
Lastly, it would be great if we can also see monochrome version of your logo with a little color used for accent. We like the pink and green version, but we would also like to see how it looks when it is in monochrome!
