Interesting update, the second and last sigs did catch my eye a little more than the others. The second for its perspective and focus, the choice to almost not showing her horns ( rather unusual when using a devil-girl for subject) did help as well. As for the last the contrast of all that white with the rest of the sig did the job.
As the Miku one, while good and using some excellent source, isn't catching my attention as well.
Usually when I do a good sig, I think than it's because of the chance or some great artwork. When the sig is bad or just ordinary, its because I screwed up somewhere
