Please stop double posting. Next time i wont merge them for you, ill just delete.

Echo's sig is alright, but the render just does not work with the cyan background, may want to desaturate that a little, because this just looks sloppy. also, try working on that text a little, because that text doesnt look very good imho.

Toasty, nice sig, buy maybe a little too blurry around the render, the text is good, but you may want to add a little bit of a stroke to it, on a low opacity to make it a little easier to read.
