I see good allignment of your string-arm with the arrow and good followthrough. I notice that you hold your fingers open on your bow hand and then grab the bow when you release the arrow. This can cause inaccuracy, as it is hard not to anticipate the release and grab the bow a split-second before release. A better plan would be to hold the bow lightly enough with your fingers that you don't have to grab it on release, or use a bow sling if you want to have a completely open grip. Many of us circle the bow handle with our thumb and index finger only, leaving the rest of the fingers open, which seems to work pretty well.
