work on blending ..

i really like your second one. nice bg and nice brushing. the rest dont "hit me" so much. some because of the text and some because the bg is to usual

i really like the 3rd and 5th one dood they are hawt i like ur text too its cool

Yea, 3 and 5 are probably your best. At first glance when I looked at 2 I thought about Target, lol...

work on the blending and don't use scanlines i like the 3rd one the most
