You payed about 15 satoshis per byte.
Currently, in order to be placed into the next block it should be about 51 satoshis.
That would mean you should have paid atleast 0.00034068, for next block.
If you are willing to wait, you can always pay less than next block price.
Your paid fee amount means you will currently wait anywhere from 4 blocks to 29 blocks.
This estimate is contingent on no new txs being added to the mempool, that pay more than you.
