gringol, the info confirms what I saw in the pic of you shooting. My first thought was your overbowed, I could tell by the wrinkles on your forehead and the alignment of your string fingers,along with you leaning your head in to meet the string. I to would reccomend finding something lighter to learn as that bow will teach you nothing but bad form. I would like you to try something to illustrate what expansion should feel like. For the sake of this deminstration use your rt. index finger to the cormer of your mouth as your anchor. Take an arrow and place it into the web between your thumb and index finger of your left hand, place you fingers of your other hand as if you are drawing a bow, as you draw bring your arm in a level "J" motion about 2-3" besides your face until you reach point of anchor. If you have done it right your shoulder blades should be together, hold and exhale lightly, now inhale slowly and deeply, if this part is done correctly your rt. arm should just pull back a little with the breath. Thats expansion. What you can do is try to achieve this with this bow but that is going to be fairly hard for awhile but it can be done if you have a mind to. I honestly would try to find something even 10#'s lighter to get my form down. Hopefully some one else on here will have some help for you also.
