Nice xcross but your last two f2l pairs need some work.
for the third pair, after your y rotation you had
You should have done U' R U' R' U R U R'
It would've happened to have left you with the 4th pair made but that's not the point, it's 3 moves shorter and 5 moves shorter QTM.
With your solution your 4th pair looked like this
You started with rotating, which is a no-no in this case, this edge is flipped correctly meaning the pair can be solved with only R and U. One way to recognize this is the sticker on the R/L face match up or are opposite colors with the R/L center. In this case the blue sticker at RU matches up with the blue R center.
Now there are a few good algs for this case, i like
(U2) R' U R U R' U R (U' R' U R) -- the U2 sets it up, the middle portion makes a pair, and the last 4 moves just insert it.
Also you can use the shorter alg -
(U) R2 U2 R U R' U R2
I still have never gotten used to the shorter alg, so I just use the longer, quarter turn only alg.
Good luck, keep speedcubin'.
