Set of Emotions

A small set of emotions made in flat. This is my second set of drawings in Figma. I somehow perceive that there is something which definitely needs to be corrected in this set of drawings. However, due to the lack of drawing experience I'm currently unable to identify the exact problem (I guess, it would be the arrangement of the components, especially that of the eyes, eyebrows and glasses, but I might be wrong). Thus, would appreciate any comment.
