Your Bitcoin Core wallet put a fee of 0.00007011 btc for a tx of size 5537 bytes. That's default, but very low priority setting for estimated time to begin confirming within 25 blocks (4 hours).

For faster confirmation next time, use higher fee - at the bottom of the Send page there is a Choose... button. It pulls up a form for setting a tx fee, select Recommended, but move the slider from 'normal' on the left to 'fast' on the right.
