Help with form, I havent really shoot sence I gaind alot of weight, I think it has thrown my form off.

No one have any thing good or bad to say?

Bear in mind I'm no olympic coach, but it looks like you may be dropping your bow arm before the shot is fully off.  You might try holding through the shot a little more if you're not entirely happy with the groups -

Couple things.  Like Hardhed said, the bow arm and drawing arm both drop before the release.  Your drawing hand actually ends up below your chest.

You are not hitting anchor with any consistency.  It looks like you are bunched up and "reaching" for the anchor.  Your drawing arm is not back and the elbow is off to the side which suggests you are not getting near full draw. Shoulder alignment is pointing off to the left and the bow arm is turned in to the body which is also going to reduce your draw and add to the bow movement and loss of stability.

I would work on the bow arm and shoulder first to get them lined up.  That will give you stability and then you can concentrate on follow-thru and the release.  Just work on correcting one thing at a time though or you might not recognize what's working for you and against you.

I agree with what Hardhed and Molson pointed out.

Practice your form by shooting at a blank bale until your FORM becomes instinctive to the point you're not consciously thinking about it.
