All the best with the wedding!
I think you will look great with that suit and most shirt/tie combinations will look good too, but I vote for picture number 2.
"...so please don't focus on the suit and shoe combo..."
Well, it's hard not to. I understand it's a less formal outdoor wedding in the morning but those light brown shoes will draw all attention to your feet. Unless you go for darker brown or burgundy shoes, the shirt/tie combinations will be irrelevant.
