Losing My Mind - Fretting Over Sport Coat Fit

Long time lurker, first time poster. That said, I picked up this sports coat yesterday at Nordstrom Rack and have been obsession over the fit ever since. I think this concern has more to do with me scouring the forums and unearthing all manners of information on shoulder styles, waist suppression, dimpling and so on. I'm driving myself absolutely insane. Hopefully you can shed some light on the situation.

The jacket itself - John Varvatos Star USA - is very comfortable, although I don't know if it's sized right. I'm 5'10", 160 lbs. and this is a 36R, made from wool gabardine. As you'll be able to see, I have a wonderfully lordotic spine - hence the booty sticking out - although I'm primarily wondering 1) if the waist appears too suppressed, and 2) if the shoulders are too pronounced. Should I keep it (and have it pressed), or return it and try for something better?

This is how it looks online:

And on me

Thanks in advance.

Thanks everyone for putting my mind at ease. I'll just go to a tailor and have them let out the waist a touch. (Don't worry, I've learned not to entertain the idea of moving the buttons.)

I guess I misrepresented my case by questioning whether I should return this number for something "better". I should have clarified that "better" meant something in the sub-$200 ballpark. I'd love to, someday, go the bespoke route but, until those lottery numbers come in, I'm a little ways away. Oh! Or I could marry rich.
