Possumjon,
I find it very hard to tell from these still photos. A video with the entire shot sequence would be better. You have a VERY high anchor, you look like you've pulled your head back at full draw and look "scruntched up". Your bow has rolled top limb forward in the release shot, indicating a poor bow hand grip, but again, really need to see the motion not just "moments in time." Your stance and posture are questionable but still again, how does all that fit with the MOTION??
If you feel you shoot well and are happy with your shooting -- don't change. But the fact that you asked, implies that you have concerns. Post a couple of videos, and we can try to help.
