I am lacking expertise in leather making and would appreciate your comments.
Exhibit A is showing the overall look of the bag. The whole bag is made of ~2 mm thick leather (easy to fold for storage). Shoulder straps are ~4 mm.
Exhibit B shows the main problem with the front buckles: (i) they are too thin (~2 mm) and therefore bend (ii) they have no stitching on the edges further compromising the rigidity. It makes the buckle hard push through the loop, as it constantly bends, it also looks ... em "unfinished".
Exhibits C and D also show "flaps" of the bag that have no stitching on the sides. Again, in my eyes, this makes the bag feel "unfinished", although I am not sure how functionally justifiable this intuition is.
I am considering for asking for corrections to be made and would appreciate an unbiased professional opinion.
