Handa has returned to Tokyo, to show his new "STAR" calligraphy to the gallery director he had punched and ask for forgiveness. However, Handa doesn't feel quite right about the work, and ends up smearing it before the director can. Could some inspiration from his time at the island help him create an even better work before the deadline?
You could just describe it as 
"a little experimentation."
"بمقدورِك أن تصِفَها على أنَّها "تجرُبة صغيرة
Kannst du es nicht mit "Ich hab's ein wenig
abenteuerlich versucht" abtun?
Podrías decir que la hiciste medio en broma.
Tu n’as qu’à te dire que tu as vécu
une belle aventure, voilà tout.
