wow thats a lot of vers.... i like 2 and 4 the swirly pentooling on the text.. i don't like so much. it looks a bit oversharpened in places as well... but i hate sharpness soo.... idunno X_X!
i dont like the first 2 at all black and white brings out the oversharpened way to much.. the v3 is alright but again to oversharpened imo... text needs a bit if work also
