It appears that she has one of the most important things down, follow through. It is so hard to tell from the pic, but it appears that she is forcing her release.
The more relaxed a release there, the better the shot. The wrist is very high, which suggest that she is releasing up, instead of straight through, fingers should be more relaxed at the release, returning to a cupped position as if they were still on the string, a possibe cause is improper alignment of elbow and bow arm, translation little back tension.
All in all, I think I may be watching her on T.V. on the Wide World of Sports.....
