How about some other angles? Looks good from this one, just sometimes a different angle shows something you can't see from broadside.
From this angle it looks like you might be gripping the bow too tightly or not "pushing" with the bow arm through the shot on the first two shots....just from the bow's reaction after the arrow leaves. Compare the bow's movement in the last shot to the 1st 2. Also can't really see from your stance but looks like it might be a lil bit open....can't confirm the "t" alignment of the torso.
When start/stopping it quickly, you can really see the concentration on your face as you release...good job.
Bottom line, are they landing where you want em to?
