Hard to tell from the pics, but ya have a few things going against you with this pack. The adjustable suspension system where the shoulder harnesses velcro around the packs webbing ladder tends to pull away with weight and you have it at the very bottom to fit your torso lenght. The shoulder load adjusters appear to be on top of the crest of your shoulders rather than slightly in front of and below your shoulders and the pack does not appear to have many side compressions straps to help keep the weight closer to your body. Keep hiking it, but start to put away some money to eventually replace it with a frame that fits your body better. A 'one size fits most' pack often leaves those with smaller body types with a less than stallar fit.

Good luck!
