Different outside, same inside

After brainstorming different ideas I decided to play around with the idea of something * I’ve heard countless time as a child about humans. People say we’re all different outside, but the same inside. People also say we all look the same, but inside we’re different. I’ve always found this confusing. Especially if you throw biology in the mix. I decided to base my idea on “different outside, same inside” because I’ve heard that version the most.
Both paintings are A2 paper size in digital form. Printed versions of them were supposed to be 70cmx58cm but the skeleton piece is smaller due printer printing it wrong. Our school's printer was really weird and this wasn't the first time it printed something in the wrong size.
