I'd say take the font from the first one and give it a light blue or turquoise colour in order to fit the background. Light velvet and the 'horror font' doesn't really fit an LSF agent, in my opinion.
Otherwise: quite nice, although I'm not that sure about the circle (planet?) yet - the edges are too fuzzy compared to the rectangle edges of the rest of the sig.
Either give those hard edges a border or let the circle edges become clearer, I'd say:)
