That shape above , is two water waves forming together and at the top its their hands coming in together ( tail of the water waves ) and the dark shaded area's in purple inside the wave form the two eyes and a smiling mouth , so all together it looks like a charecter face with sharp thin eyes and lips and smiling .
Hope you like that logo ( icon ) formation together.
Would like to hear your feedback on any of above and if you want me to change anything or try anything of it of you like that direction.
