Character Design Sketch 2

I've done a set of two characters but wanted to find out which shape suits which expressions more. So I've duplicated the initial set and changed the emotions and decorative icons of the characters.

Here's the outcome:

Picture 1: Two sets of introvert and extrovert character design.

Note: Set 2 is the original sketch and Set 1 is the duplicate. I've asked some classmates and non-classmates to help identify and to give feedbacks on the character designs. Of five (5) people whom I seek feedback from, four of them mentioned that they prefer Set 2 and can relate more with the shapes and emotions, but only one chose Set 1. Most importantly, all five do not specify or identify which character is more feminine or masculine as opposed to my previous character designs, so it can be considered a more successful design this time.

Feedbacks received:
- (Set 1) Head looks more balanced as opposed to Set 2 with the droplet shape and sun-like symbol too 'heavy' for the character.
- (Set 2) Expression/emotions suit head type better.
- (Set 2) Able to link the icons (heart and sun-like symbol) with overall character design, although the head design will not make any difference without the icons.
- (Set 2) Left character's head shape - like a rock suits the awe look on the character, right character's head shape - like water droplet suits the cheerful and carefree look better.
- (Set 2) Can link icons and head shape together, but to take note if heart shape will make character look feminine.
