Thanks for this - for #11 we like the use of the power button but want to stay away from speech bubbles - they seems too much like a chatroom / messenger brand. #12 has got us thinking we like the idea of a character/avatar - but this guy looks a little "blobby"/pear-shaped.
Can you work this forward by keeping a power-button head (perhaps at an angle?) but with a more "dynamic" body.
I really like the avatar, but I would like the body to appear more like a stick figure, possibly a side profile, sitting down, maybe holding a laptop.
