Designing logo and layout for a educational card game

C'est ce qu'une entreprise en/au(x) Malaysia recherchait pour leur card design

I have created a card game that involves the students to learn about macromolecules (nutrients required in the body such as nucleic acids, proteins, lipids, and carbohydrates). The game and cards are all in place, but I need a unique, professional, and attractive design for the cover of my playing cards, and how each card should look.

I need a logo design that looks uniquely professional as in not too childish and not your typical educational "fun" type. But at the same time, should resemble science as the game is in a science/biology class.

I would like to see the cover fully in black, with designs that contain subtle bright colors.

Please see the attached file to see the game. The design I have is too simplistic and amateur. I need something that shows a better professionalism in the game. Voir plus
