Can we try some other colors maybe a dark green or apple (company) silver that makes it look even more clean? I don't think were stuck on red and black.
I'm a big fan of the icon with exclamation mark/text bubble. Would it look good to take that exclamation mark in the icon, flip it upside down and use it in the "k" or "i" in speak social?
I agree on the k as well. It was just a thought. Not to ask too much work from you, but can you take the icon from #23 exactly like it is in its box and flip it upside down for the "i" in #44? I know it will make the conversation bubble upside down, and that's ok. I'm at this point just being picky curious, but I love that concept that you've developed.
