My lifestyle xD

Since I'm kinda drawing roughly off a bad pic I took of myself at a slightly different angle, I would appreciate some help xD. Like idk if anything I'm doing is right or close to it. Btw I'm sitting on a wrinkly couch xD. I wanna do something with the right arm but idk yet. Just wanna know if its in the right spot(his shoulder). So any feedback would be great :D. Also this is rough so the background is kinda just quickly put there QuickTime so lines aren't straight and yada yada. I'll fix them up before actually finalizing it.
