Coming from the perspective of an illustrator: The use of the chosen colours is very effective; it adds to the strength, readability, and overall design and format of the piece. I particularly like the fact that the title is rotated 90 degrees clockwise and formatted against the layout and dimensions of the trifold panels, which helps it stand out. The font is an incredibly strong and vivid choice for the MOSH expanded community and publishings.
My only criticism is that, for a cover with such a strong overall appearance, I had hoped to see more individual pieces of artwork carried throughout the deeper design. As for the logo in the top-left corner of the cover, it feels somewhat out of place and disrupts the presentation of the title text. Had I seen the cover sooner, I would have suggested making the logo blue and fitting it within the letter “I” at the top so it would stand out against the white lettering, rather than placing it inside a separate box of its own. Alternatively, the logo could have been positioned solely within the orange band at the bottom of the exterior page.
