When doing animation, you want the pics, if numerous ones are used, to basically be identical, so the feel is as if the same exact thing is moving around. With the sig on the left, you have 3 different images that look totally different with aspects of quality and style, ruining the true feel of a solid identity being involved in the animation. Turning my focus to the BG and the font, the color is alright, but the balance isn't, and the font doesn't look good at the very bottom like that.

On the second sig, the animation is too simple to really be appealing. The BG is has a good flow to it, but needs a more noticable border to have complete balance. I'm thinking if you had made the font a lot lighter, it would have made the animation feel like it's more a part of the sig.
