The first step to drawing any character is sketching the outline. In the case of Luffy Gear 5, this can be a daunting task given the complexity of his form.
With the outline sketched out, the second step is to add features. This is the stage where you'll start finalizing Luffy's features like his eyes, mouth, and nose.
Once you've got the outline and features down, it's time to ink. Inking is what brings your sketch to life, so take your time and be patient.
Now that the inking is complete, you can move on to coloring. Before you start, visualize the colors you want to use for Luffy and his surroundings.
