Dude, you are a mess.
my bow string is crooked
I also heard that the string should be touching my chest as an anchor
my back looks like it's bent back but when I try to straighten it out it feels awkward. If it is wrong how do I fix it?
I am kidding, sort of. I HIGHLY suggest going to a pro-shop for a lesson or attending a local 3-d shoot in your area (I am sure there is one close to you this coming weekend!) and ask one of the higher scoring guys for a little in person help. Most guys will definitely take the time to help a new guy.
My suggestion would be to do either of those things as soon as possible as the more you practice your "bad habits" the harder it will be to break them.
One last, but very importantthing ... that bow is to long for you by over an inch. One of the reasons you are leaning WAY back like that and your natural anchor point is probably not that far back. It's almost like some one sized you up for that draw length based on you shooting from the string and then you put a loop on. I HIGHLY suggest going to a pro-shop ASAP!!!! You'll be amazed at how a little in person instruction and a properly fitting bow will help everything!
I guess Rack Attack and I we writing at the same time! Shorten that draw length!
