I like the font, a lot of english blackletter has a gothic creepy feel to it, which is in come respects what Spectre is all about right? Anyway, my thought on the sig is this, decide what feel you want the sig to have and adapt everything to it. If you want it to be creepy, make it creepy. Maybe increase the size of the pic on the left so that those hooded eyes are a bit bolder, perhaps increase the contrast so the darks are dark. I don't think that square/pixel effect really makes any sense in this sig, and the lines around the text just seem to distract from it. Perhaps you should grunge it up a little, or use harsher tones to bring out that darkness. Absolutely fix that letter spacing, the "S" is way to far from the "p." And I think you need to work a little on the drip effect.
