Please don't take offense, you asked for feedback, so I am assuming you mean honest feedback.
I will start by saying I doubt I would never take this on, so it's not like I have a similar cake I'm comparing it to!
The hair, gloves, veil, dress, jewellery and bouquet(?) all appear to be fake... gumpaste pearls and flowers, and isomalt jewels are all very simple, and really would have added a huge extra punch to it.
Making the hair out of textured fondant would have made a huge difference as well, even if it didn't look as realistic. As someone who has had to wear wigs, I know that those hairs can get everywhere!
The dress, gloves and veil I am aware would take an enormous amount of time and money to make edible, so may have been way out of the bride's budget, or your time limits.
Since you were custom making the figure, I would have had her hands together, so they look like they are holding the bouquet. Instead it's a bit stiff, like a mannequin.
The shape of her upper body is flawless, right down to her shoulder blades! And her hands are wow! How did you get the gloves on without messing them up?
Please understand, preferences differ, and my personal one is that everything on a cake be edible or foodsafe.
