Could someone critique my work-out routine? Your routine looks basic, for the most part. I suggest you to cut down on shoulders. They get trained in every exercise you do and IMO, it's overkill.
I've been thinking of changing the smith machine shoulder press for the barbell overhead press...or should i change it to seated DB press? I have noticed my traps haven't grow that much...so I was thinking of starting to do barbell upright rows? You'd want to do either DB or Barbell shrugs if you want to grow traps. Dead lifts also help your traps grow as well. Barbell upright rows target your deltoids more than traps and they're an OK exercise as long you're doing them light. Doing them heavy is a sure-fire way to get your shoulder injured.
And my last question, I have noticed my back has been growing pretty big... I don't really want a huge back 'cause of my height [5'7'' tall] which it would make me shorter? I just want a lean body. I've been thinking...that the reason that it seems pretty big, at the moment, is because I'm gaining some fat while bulking. So, it will look better [not that big] once I start my cutting phase? Am I right? Weightlifting won't make you any shorter. I dunno where you got the idea that a huge back will make you look shorter. Yes, your back will look much better once you cut down. Your back will look much leaner and definition will be more pronounced. That's the best thing when cutting down body fat.

What's your goal here? Do you want a bigger chest? Bigger arms? Do you want to get stronger? Once I have your specific goals, I'll come up with a 4-day split and see whether if you like it or not.
within the last 3-5 pages I wrote notes on flat barbell pressing though ~ plenty of people avoid it though.
~i got it.. fix my eating habits.. and workout O.O
i'll read the last 10-20 pages for better understanding
