Hi! Thanks for the feedback. Much appreciated.
The icon in #64 actually has a gradient, but I apologize for not making it more notorious, which is why in #77 I've increased the contrast between the light blue in the center and the darker blue in the outside. Also, to make the effect a little clearer, in #78 I've brought the elements in the icon a slightly closer together.
Font is a little bolder in #78, which gives it more strength in my opinion.
Let me know your thoughts.
At your service.
