With this design, I attempted to portray sound without onomatopoeia's or words, but with just visual representation alone. For the final product, I chose to use the sound of creaking steps, late at night while the rest of the house was dormant. I portrayed this with a girl sneaking down the stairs, and yellow to bring the attention to the foot reaching for the next step. Hopefully, the yellow (since it contrasts with the dark black elsewhere) will draw your attention to my 'sound'. (:
