Need help

[blahblah]

I dont know what to think anymore. I am only 17 so i figure this will go away. But im 5' 11" 148lbs. Thats fairly skinny or so Im told. However I look in the mirror and take pictures and  I ask myself why my body sticks out as much as it does. Also it seems my back is bigger than normal? I just have this overall feel that my body is oddly shaped and I dont know what to consider myself. Maybe Im not used to being a bit on the low weight side cause I used to be bigger but I dont know. Heres some pictures. You guys tell me what you think and what I should do.

i think there's a very thin/slight 3" or so of something that doesn't belong, and if you're lucky maybe it will, supposed to in most cases anyway.
