The first signature is a bit dark, but looks really nice.
And I am in love with the second signature, but it would look even better if you would take the entire signature(minus the text), flatten it, Filter>Blur>Gaussian Blur 4.0 and then Edit>Fade Gaussian Blur...>Soft Light. You could then (but this is only a personal preference) sharpen it once more, that might look somewhat better. But I definitly suggest to blur&blend it. It gives that extra Roy Mustang feeling to it.
You can of course try something else than Soft Light, but it will probably look best on this signature.
