Hmm, nice I like the first one sorta, but I really like the second one much more.. even though its sorta empty, go figure... heh
The text in the second ones good for a first try man, but the first one seems more abstract to me.. All together they're both pretty basic if you want a tip though..
Try to use a border to accent the features in the color scheme you use in your sigs. Also try to upgrade your image editing soft to photoshop 5.0-7.0 or possibly at least Jasc software.
