all the last three are great... love the flipped part in the very last sig... and the text too... the avril is great, cool bubbly effect and great colors too... the evanescence one is a biiiiit too bleak... like kind of a lack of color, either add depth and darken somehow or add some color to contrast... or like increase the ones you already added... the red, blue, green and yellow spots...

and of the previous 3 i love the third one -the one "where there's love..." - it's reeeeally good... the second one is all grungy but a bit too plain... and first one isn't that good, kind of messy and a bit too smudged...

but love the latest ones
