Overall, very nice. One simple thing that will fix/improve things immediately is a better fitting shirt. I'd try a shirt collar 1/2 size smaller. A higher fitting shirt collar (and a better tie knot) will make that tie disappear at the waist. Also, a better shirt collar will bring more balance to the coat. . The shoulders look clean and well fitting. The coat seems to fit you well--waist, length etc... You are slim and probably would have no problem fitting into any off the rack coat or suit. Small detail: it looks like there are flaps on your pockets. If so, one is tucked in. Also, with that basic, neutral color of the coat, you might want to experiment with a darker tie.
It's not the fancy, expensive label. It's the fit.
Here is an excellent article, that I need to re-read myself, by Thomas Mahon, an English bespoke tailor. It has lots of useful and sage advice. http://www.englishcut.com/archives/000101.html
I hope this is useful.
