"Dollar Bill' character with '$' sign as smiling mouth. #2 slightly more obvious $ sign, #1 more realistic treatment. Holding books to reference learning. Let me know of any changes, feedback you have, happy to make alterations.
I like these--anyway to make them look more like a dollar--not too detailed thought. I see how the mouth is a dollar sign; but if you don't catch that--then it looks a bit scary..ha!
How about not holding anything in his/her hands? The thumbs up is okay--but maybe take the book out of other hands?
Can we color it up a bit? too much green--maybe different color shoes, or wearing gloves; perhaps a ball cap?
You are the professional--I am just talking/brainstorming out loud.
two more entries - still may need to think of a way to subtly look more like a dollar bill, but don't want to 'overdo' it. Can change hands to colorful gloves if you'd like?...
#11 changed to look more like a dollar bill with same color hat/shoes/gloves #12 a different concept, character is a $ shape, same style as my other drawings
