It's a good shot. Were you trying to get that look just as it is? I know you were trying to get a streak on the cue ball but I think if you had a bit less light on the subject (pre-flash) the effect might have been a bit better. Also if you had pulled back it might have been more apparent what was happening. It took me a second to realize what was going on in the pic.
Thanks for posting this. It's helping me to understand 2nd curtain as well.

Very cool!!! The motion is great, love the way it turned out
why dont you try increasing your speed to 2s , then adjust your flash to a lesser power ( Rear ), start with a low ISO at 200? if its too bright then adjust your aperture one at a time , hopefully it will stop the cue clearly at the same time leave a motion trail ..but for me its quite good you have that excellent result ...
best regards ,
