Hi there, I hope you will enjoy your contest here.
I have uploaded a couple of designs for you, here's the explanation. #1 is a figure arising as a star, #2 is a group of figures blossoming there talent. #3 is a nerve cell (stands for adrenaline, emotion and speed) with 3 figures of which one reaches for a star, and in #4 a figure rises from an explosion to reach a star, as a metaphore for how booming one can become.
I don't know if any of the entries is in a direction that you like, but I'm happy to make any adjustments during the tournament.
k/r, Peter
