That's nice. Here's a few tips you can use if you want:
The border could be black, or another color. This keeps the focus on the color of the sig instead of its distracting frame.

The color needs to be desaturated and mixed with another soft one to make it look soft too.
You can try using a Selective Color layer. (Layer>New Adj. Layer>Selective Color), and mess with all the sliders until you get the look you like.
Plus, I think it would be a little better if the flower had a little space from the bottom of the sig, like it has from the top.
