First navy blue suit, feedback needed

Been trolling the forums for awhile finally got around posting. As this suit is already done im here to see what should or should not have been done the next time i plan to commission a suit. This was made with the help of members on a Malaysian forum, many thanks to those who commented i am currently studying at Melbourne Aus, but the suit was made in Malaysia before i left #cloth : Holland and sherry Dark navy blue , 12oz, s120 *Single breasted *2 button *4 sleeve buttons *Swapable buttons *notch lapels *Double vets *Half lining *pick stitching *surgeon cuffs Fit pictures Warning: Spoiler! (Click to show) Detail shots Warning: Spoiler! (Click to show) As i am new this being my first i did not do enough research on the pants, i only told the tailor i wanted them *slim* if im not wrong they are non-pleated, belt loops, no side adjusters. Comments and criticisms are welcomed PS: As one can see that the links on the buttons need to be redone,can anyone suggest a tailor in the Melbourne CBD area that can resew them for me?

im still very much clueless about pants, ill try posting direct links for the images and see if they show. That was the only tie color i had that compliment the suit, bought it years ago when i was much younger.

Switched image providers do tell if they still dont show

Thanks all the for comments, seems that the pants are getting alot of attentions. I think i did wear them a little low. I would like some critic on what i might convey to the tailor next time i were to bespoke a part of trousers. As in what are the main characteristics of a fine bespoked pair. The brass buttons are for with jeans and casual shirt
