Play with erode and dilate settings in vdb reshape SDF node and with the vdb smoothing iterations. You can increase the resolution of the vdb and perhaps use a point replicate so the splash areas have more points to sample from.

One more question when i m making the mesh in vbd its coming too compact,i want to get  smaller details,is there any other way around to mesh the particles.

Jenny, I'm really curious how you went about acheiving those beautiful inky splashes on your vimeo. I've had trouble getting those nice flaring shapes and stringy-ness in Houdini, coming to it from a realFlow background. I'd love to hear some tips, scene scale, pscale etc.
