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.
Kind Regards.
