You should change the text. It doesn't match at all to the overall sig. Also adding a border, even a 1 px black border, can make the sig really stand out. And IMO, you should take off some blur from the renders red 'collar'.

You should make that whole sig one color. The colors don't blend in. Also, it'd probably look nicer if it was smaller. I don't like the text at all, so work on that.

The text on the updated one looks much better. The cyan and red don't go that well together and the cyan looks too bright (or that just might be my monitor settings). Maybe lower the saturation when you color it?

Yeah... you pick two colours that are at the opposite ends of the scale (or in this case the hue saturation slider) Even in your current sig, you've got purple and bright green, two very different colours.

I like the second one the best, though. But the Cyan's still too bright and a part of the render is blurry.

If you absolutely cannot scrap the blue, just darken it... And you should fix the render. If you do that, it'll look loads better.
