What program are you using? Photoshop? Many members using GIMP to create signatures, but I've personally only used PS... so I'm not sure how helpful my advice will be, haha.
Your 2nd one has good dynamic. I've always felt like movement is important in a sig. Otherwise it will just look like an image plastered onto the background. The lines in the second signature lend the tag a sense of motion and depth. I like it!
That said, I still like the first one. Unlike the second, it's very soft around the edges (not too sharp), and the girl blends in better with the backround. In addition, the moon doesn't stand out as much in the first one as it does in the second. In the second, I feel like there are two focal points because both the girl and the moon are so visible.
A good way to break up monotonous feel of your signature is to use more color. Your stock image has plenty of purple and blue hues to choose from; use them. Pick up a light pink/purple and a darker hue and work them into the background. (Then again, if you're going for a dark, mysterious feel then the color palette you currently have is alright.) Once you get a stronger feel for colors, you can start experimenting with more shades!
The best way to improve, though, is just to keep on practicing. Mess around with the buttons and functions. Online Tutorials also offer good advice on techniques and ideas, too--so don't be afraid to hit those up.
Keep up the good work!
