If I cancel my account they will continue to charge me or because my subscription ends in February ??
We can see that you have stopped your Adobe Stock - 10 images a month (one-year), paying 29.99 USD that was due for renewal on 30 Aug 2017. (It's not February)
Once you cancel Stock Subscription, you have time till your next billing cycle to license-download any left over credits else the available licenses/credits would expire post next billing date. Images that are licensed-downloaded are in your license history to be used anytime then.
As per your account, you have been charged recently- 30th Nov'16 and there are still 10 licenses left to be used so we would request you to utilize the left over licenses before your next billing cycle- 30th Dec'16.
Hope this helps.
