hey, i was wondering if anybody could help me get more shoulder flexibility because to be honest mine isn' good. I can do backbends but ic=ve been told i need more flexible shoulder. Could somebody please help?

try doing back bridge and then straightening your legs out so your weight shifts more to your shoulder and holding it. You can do a bridge with your hands on the floor with your fingers touching a wall and then try to shift your body as close to the wall as possible. Another shoulder stretch I do is sitting on the floor and putting my hands down behind me slightly more than shoulder width apart, and then shifting my butt forward as far as I can. For further stretch you can then lift your legs up into a pike position.
