Zich serieus, sterk en opstandig voelen, vuist maken, protesteren of vechten voor revolutie - Stockfoto’s en -afbeeldingen

Feeling like a happy and excited genius after realizing an idea, cheerfully raising finger, eureka!

Holding cheek and suffering painful toothache, feeling ill, miserable and unhappy, looking for a dentist

Looking concentrated and thinking hard on an idea, imagining a solution to a challenge or problem

Looking concentrated and thinking hard on an idea, imagining a solution to a challenge or problem

Smiling with a positive, successful, happy attitude pointing to the camera, making gun sign with hands

Looking happy and excited, shocked with an unexpected surprise with both hands open next to face

Looking happy and excited, shocked with an unexpected surprise with both hands open next to face

Looking proud, confident and happy, smiling and pointing to self or making number one sign

Looking puzzled and confused, biting lip with a nervous gesture, not knowing the answer to the problem

With a concentrated look, wondering with a doubtful expression, looking up and to the side

Feeling shocked, happy, amazed and surprised, looking to the side with open mouth

Laughing cheerfully and confidently with a casual, happy, friendly smile
