You need to start by studying Gojo's character design and features. Pay attention to his unique hairstyle, facial expressions, and clothing. Then, practice sketching basic shapes and proportions.
First, get familiar with the DC characters you want to draw in chibi style. Then, break down their complex designs into simple forms. Add lots of charm and personality. Don't be afraid to experiment with colors and shading for a fun finish.
