Any High Speed Sync Flash or ND Photos?

Here is a couple of my flash photos with the X100 and one ith the ND filter all at f2.

The one with the possum and the rat was taken at a distance of 1metre. The shutter was 1/1000s sec. High speed flash has so much potential but very few cameras can do it and the potential for creativity is limitless. The first is ND filter in very bright light shot wide open. The second photo of my wife is just with fill flash at 120th sec. SOOOC JPEGS no PP.
