The statement regarding the Hot Topic shoppers is valid, being that most of the materials they sell are nostalgic based themes, the logo DOES make for someone to grab it up.
But, as a cartoonist, what you have to consider is where the comic book falls in the stacks. You'll have to keep the TITLE of the book on the cover, obviously, but it should be placed high with the same type/font as you see on the poster mock-up of Ray at the front of the GB.net site…the usual font.
Faded into black and very large almost covering up the entire cover should be the No Ghost Logo (I liked the idea of texture added into it).
But, as it was mentioned, a sample of the story should be included as character art on the cover as well. Why? To indicate it is NOT the same old RGB or EGB stuff; plus, it's all going back to the old khacki suits which many of us relate to ‘being’ the actual suits and further differentiates this NEW work from the tired old stuff we've seen for so many years.
The cover has to have some action to it to capture the attention of the purchaser, and I think it can be achieved in the artwork.
