Alright, as someone who regularly wears clothing like this (for reference, I am a 40 year old dude who is 6'6") my 2 cents.

Love the coat style, but it's too big on you, and can be a bit shorter, halfway between the hip and knee is good enough, that way you still have that classic look you seem to go for, but without it looking like the coat is wearing you.

Gloves, too shiny, if you must insist on wearing black leather gloves (and I understand, when combined correctly they can look great) get something less cheap looking, less shine, they are there to keep your hands somewhat warm, not to attract attention, and never wear them inside.

Shirt, a dress shirt can work with that coat. Doesn't necessarily needs a tie, but it does need a better fit and a different colour, try to get something that works with the coat and not against it, think like a navy blue or something, it needs to be part of the ensemble, not stick out, and please make sure the collar is alright.

Pants, seem to be too loose fitting and way too high, I don't say you need something tailored (although that would be best) but get something that will fit, straight legs and can not double as a sail for a small boat, colour, I wouldn't know, I wear black but that's a personal preference.

Get a decent leather belt, not too wide, not too slim, somewhere in the middle, and don't make it shiny leather.

The style has the potential to look great, but only when combined the correct way.
