I have like 10 sets that I pick from -- just depends on the angle and style of haircut.
I also use the grassblade brush that's on the bottom of the default set
might try the desaturate/overlay method on the render to help it blend in more. also, try placing a white, full opacity, drop shadow on the font to help bring it out.
bg is nice - but just work on blending in the rest to help it fit better...
