Hi, I have made some additions to the faces like brows and eyelids which help convey the emotions, I hope that it is fine with you. Shapes of hats also relate to the emotional state of character. I have done work for laser cutting before, so I feel confident in following the technical requirements you need. Note that these are only sketches, the artwork will be cleaned up and perfected in Illustrator. Please let me know if you like these sketches and if you have any suggestions or feedback. Thanks.
