The messy bartacks kill it for me. I've always loved EG because he used proper bartacks and they were always subtle. Those double 'x' style bartacks are cool, but make it look to Affliction brostyle for my liking.
I know I do EG different than most here. EG to me is just easy to wear stuff for everyday things. I've never got into the more artistic side of the brand, but I love their everyday stuff.

I think the tie looks good man. Nothing wrong with keeping the same color palette, you could change it up with your pants - but me, I'd probably wear olive cords or something with that. Maybe I'm too uniformed though with my EG looks :P
I would cuff the pants and make them break right at the top of your oxfords. I feel like it makes the type 41's look a lot more flattering. Love that work shirt, one of my favorite ones. Good call on that!
