The transaction fee is too low. Unfortunately you decided to use blockchain.info's wallet so there is not anything that can be done about.
Try to use ViaBTC TX Accelerator:
https://www.viabtc.com/tools/txaccelerator/It should work, because I calculated the amount of BTC per KB and it should work without CPFP systems or any new inventions. Your transaction ID is over addresses label, but under Transaction inscription. Copy TX ID to ViaBTC accelerator system, type captcha and when ViaBTC mines his block, it will (probably) include your TX.
