I’ve received comments about these two designs:

The left one:

I’m not like a *regular* mom, I’m a *cool* mom.

Too many tattoos and they should be executed better.

The right one:

1st rule of magic: Always be the smartest guy in the room.

It is not clear the idea of “smartest”. May be a good idea to make the guy into a scientist(someone smart).

 

Hence I made the changes:

Lessen the tattoos and made it more obvious that the son and her have matching tattoos. I made the picture more contrast as there were grey tones.

I also put a old fashioned microscope and made the body of the character be seen more. He is wearing a science lab coat.

 

These are my final images along with my tote bag print and silkscreen:
