You've placed TWO 1s in box 9. The one in r7c7 is not valid as 1s in row 9 are locked to box 9.
I found this puzzle pretty easy using lots of hidden/naked singles, a few locked candidates and naked pairs, and an xwing (maybe not necessary). Find what you've done wrong (or start again) and you might complete it without too much hassle.
