One more thing, while working out sometimes on shoulder burns more than the other even though im trying to do the movements as smoothly and evenly as possible why is that? i also feel the burning sensation while im working out but later on im not sore, is that good or bad? Thanks

You probably want to add deadlifts. Squats, deadlifts, and bench press are the 3 pillars of a solid program.

Just a tip: "Pump", "burn", and soreness are not reliable indicators of a good workout, nor does their absence a reliable indication a bad workout.
