It isn't an improved signature if it's a completely different signature y'know... :P
Anyway, the text fits only partially and doesn't have any "oomph" to it, the "shadow graphics" text has really poor quality, is it a stretched image?
The background is messy and the edge near the center of both blades have a weirdly pixelated pink-ish line, just like the whole signature's border.
By the way, this signature lost the flow the other one had.
Suggestions to improve:
1) Don't rely on text unless you have to, in the signatures you made it takes up too much space and doesn't look neat enough to justify such a presence.
2) Avoid slapping that "shadow graphics" text in the signature: place it carefully, make it look neat (play with transparency and layers to start out) and make sure it's high quality when placed.
3) Respect the rule of thirds, it's free "style" points.
4) Have layers interact together: two blades (which are the excact copy of each other...eehm!) put on top of a messy background ain't gonna cut it (got it? I'm such a trickster! )
