The last step of the creation of a manga page is lettering.
Depending on what kind of manga or comic you make, it‘s not necessary to have a ‘typical‘ comic font consisting of capital letters. But it‘s wiser to use regular fonts unless you have good reasons not to do so.
Try to find fonts that visually complement your comics scenario and atmosphere.
Keep in mind that the text is also a part of the whole page layout.
For example, I used the blue underlined soundword as an "arrow" of sorts to guide the readers eyes.
Some of the soundwords have been drawn with a brush in order to visualize the roughness of the sound.
