A powerful logo for a business executive E-course

Leader is a person with decision making and strategic thinking skills. A person who solves the problems. So I came up with the concept of a business suitcase in the form of puzzles as a symbol of solving problems. Also, puzzles speak about communication and team management.
It is bold, rectangle shaped design that communicates power and strength. It develops an sense of stability, balance, and reliability. On the other hand, rounded corners and puzzle contours make overall feel a bit softer and not too masculine.
