The pants have a little more break than I like...but you're also a lot taller than me. And as has been said, they could use pressing. Of course if you look at the arms of the jacket it appears that they need to be pressed so maybe you'd just been in them for a while. I can't tell for sure due to the glare but are those solid black pants with a pin striped jacket?
I like the length of the sleeves. I've never much cared for having the shirt sleeves hanging out below the jacket. To me that is just a leftover from a long time ago when it wasn't very easy to clean suits (the shirts were easier to clean so they hung below to take the dirt instead of the jacket). The shoulders look pretty good but I'd need to see you move in the jacket to be sure. The pocket square matches well in this case. I do see a little pulling around the middle due to it being buttoned. That makes me wonder if you wouldn't be better served by moving up to a 40. But if everything else fits a tailor could probably let out some around the middle and make it work. The length of the jacket is also pretty good and the notch lapel is very neutral so you won't see it go out of style anytime soon.
I don't particularly care for those widespread collars on the dress shirts. I find them to be hard to fill correctly but again that is my preference. I try to make only the knot of the tie show at the collar at the is much easier on a more narrow collar. The tie is a nice color and the pattern makes a good contract with the jacket. I generally don't go with a bar however because they don't usually go all the way across and that just seems unbalanced to me. I used to use a tie tack but anymore I just go without. The jacket will generally keep it in place enough and there are loops on the back to hold the other end of the tie in the correct position.
How's that for being critical?
Really, it fits well enough that if I saw you out and about I wouldn't think anything of it. You just asked so I gave you what I saw since I looked for it. Oh, and polish your shoes.
