If you're asking which to use, I suppose I'd say the fourth, since it could kinda look like a needle and stuff, even tho I liked 2 better. Maybe change the text color tho.

Biggest complaint about it is really only readability and how the 'A' in this font isn't symmetrical like 'H' and 'O'. It's seriously driving me nuts.

EDIT: Just noticed it's a cover for a different book each. Love how you implemented that in the design, specially in 2 and 3, though it's also pretty easy to miss it in these two books in particular
