Dude nobody wants to see your pubes - try leaving that out next time. Other than that you look like you got nice vascularity and lean muscle but you definitley need to work on the chest. I'm a big fan of doing pushups - all the different variations - wide grip, diamond, elevated and the normal way. You can get some nice size on your chest by doing them alot and you will also get stronger on your bench and other chest exercises - give them a shot and keep working hard!
