I'm a big fan of one-button jackets, and I like them to have notch lapels as long as it isn't for formal wear. It looks a bit tight across the chest in front. The lack of vents calls attention to your behind. What that jacket needs is nice long side vents, but that won't happen. The jacket is much too tight across the seat, so you might see if there is fabric to be let out to make it less snug. And make sure you have the sleeves taken up a little.
