Lightening the color of the tie may enhance this look, contrast works as well; I'm jus' sayin'. Also, a slight shoulder extension should be considered as the effects of your RCA on the fabric is noticeable. Perhaps, it is the weight of and drape of the linen fabric on your shoulder. Folks on LL often advocate for heavier weight linens though I've not closely followed their discussion.
You could flip this look by rocking a DB in sand which I think is an elegant look for summer.
