Thanks for posting these. These photographs are excellent and show the finished garment well. the only extra one I would suggest is one showing the whole of the interior of the coat as well.
In many ways it looks quite good but;
The sleeves look way too short - especially the left one.
There is some rumpling at the back - not too serious and most would not even notice it.
The trousers do not look quite right in the thighs but that might just be how they are sitting on your shoe - see the sixth photo. Nothing to worry about though.
Next time ask for a heavier lining. I have noticed on several tailors (Not Chan.Yao or Yu) that the lining is far too lightweight which allows the construction of the coat to be seen behind which is not good at all. Even in HK that does not make the coat too warm.
On detail, I assume that the trousers have the standard pocket (for HK tailors) in the waistband and the coat a ticket pocket? I assume that you did not ask for any more nor did Lee Baron offer them.
The sleeves are the one to look at but otherwise it is a decent looking suit, well done.
I look forward to you posting the same array of views of the blue suit.
I think the sleeves on the shirt are simply too long. Especially on the left side, where the collar has pulled down. I don't think the issue is the suit. I admittedly do find the back somewhat "hourglassy" - but perhaps that is simple your figure... do you work out your shoulders/back more than your chest/arms?
