I really like your choice of fabric here : you look great.
If I may, though, I think two slight design tweaks would make future suits look even better.
Firstly, raising the pockets a little; and secondly opening up the front quarters a touch. I think the combination of those two edits would lend the silhouette some subtle shape and render it less 'boxy'.
A previous poster mentioned dropping the button stance but, imho, that element looks superb as it is currently.
