yup, guest0043 is my solid winner for this one.
LS's sig is overflowing with lots of dashing colours and vivid images. LS has used pretty much every overlay/hue technique i know, the graphic he chose fits in perfectly with his bright "sunset" mood, combined with the great text choice, its great. the only thing i can possibly see wrong with it is blacking out to the left of the sig, it seems a little out of place with all the colours, then theres the leaf brush around the text, i wishehs people never use that damm brush, looks so lame to me ;O
CJ sig is also good. the night elves graphic is well chosen and displayed, and the background seems to flow from her, giving her a mysterious look. but it still flaws at places. The right hand side of the sig is left empty and rather bland. but the biggest letdown is the choice of text, calligraphy never works for me, it makes simple letter look odd, eg, your 'J' looks more like a reversed 'B' and the fact that the text is a tiny two letters also lets it down, text is vital in a sig as sigs are designed to display your name, not just plain visuals, if you placed your full name there and a slightly better font, it'd be great.
overall, im going with LS's sig, because i love the clash of colours, the graphic, followed by good text choice :O
