You only paid 5.04 sats per byte, which is definitely quite low. Next time a safer tx fee would be at around 18-30 sats/byte as long as you're not in a rush. I personally don't use blockchain.info's wallet so I really don't know if they allow custom fees.
Anyway, I placed your txID on a transaction accelerator so hopefully it gets through. I really don't know how long though, probably need to wait a bit until all those queued transactions goes through.
