First WAYWRN post actually, not too bad I think Warning: Spoiler! (Click to show)
Welcome! Not too bad is a fair assessment. The triangle of shirt/tie showing beneath the button is less than ideal, and a less boldly patterned shirt would work better with the tie.

That's a challenging fabric, ace, but worth the effort. What you've chosen seems to work well. (I'm assuming that's a blue shirt.)
