Hard to tell exactly with the angle of the picture, but it looks like your draw length is a tad short, this brings your back elbow up above the line of the arrow.

Couple of other things I see, all fairly minor:

- bow hand is grabbing the bow, just relax the fingers so you are not actually holding the bow.

- elbow looks rotate in a bit, probably due to bow shoulder being up, try and roll the bow shoulder down a bit, this will roll your elbow out a bit, not bent, just rotated.

Overall it looks good.
