ABC's Concept, Moodboard, Sketches

My alphabet will be a graffiti-themed book consisting of 26 letters relating to typographic terms. Each letter will be constructed in the style of graffiti, with a bold color palette to accentuate the street art aesthetic. My sketches are rough, and do not include all the text that I plan to include on each page, but they give an idea of how I plan to lay out each letter on the page.
