Nice job of combining three solids (tie, jacket, square) by diversifying texture. But I wish the square were a bit different. It's in good taste, but perhaps too predictable. Also could stand to be darker and bolder to reference and balance the tie.
Your pocket square is angled the wrong way.
Don't like. Consists of only two bold, primary colors. Borders on cartoonish. Make the blue or red more subdued and you'd be okay.
Not in good taste.
