MUCH better and more presentable.
I'd say you have a good outfit going, with good colors, just make sure the shirt is freshly and well ironed before the interview. If you don't have an iron, you suck at it, or you have an ironing phobia take the shirt to the local dry cleaners to have it laundered and pressed, normally only costs a couple bucks. If you want get it lightly starched while you are at it to keep it looking presentable longer (you can ask them for a recommendation, different fabrics and blends take different amounts of starch better).
The difference between a crisp well pressed shirt and a sloppy wrinkled one is night and day. It's one large step in appearance that gives an aura of attention to detail.
