Shirt should be lighter than jacket, and tie should be darker than shirt.
Shirt collar is too spread and should be narrower to go with the jacket lapels.
tie is too wide for jacket lapels
tie has incorrect knot, should be double four in hand.ir other asymmetric knot to go with narrow tie small non-spread collar and tie space
Jacket breast pocket needs a pocket square. White Linen / cotton is cool
There is something going on with the back of the sleeves of the jacket, maybe the shirt sleeves are rolled up inside.
The jack pulls across the back at shoulder height
The Jacket sleeves could be a little shorter or the shirt sleeves longer, (probably both) so the cuffs show
The single button pulls across the right side so the jacket is a little tight around the waist. seems to be taken in too much at back centre.
The jacket skirt is slightly long as measured at the knuckles, It is probably a Long and should be a regular
The trousers have a lot wrong with them.
Have multiple breaks down the back of the leg, and there should be none. Adjusting your front waist usually sorts out back breaks.
Also have multiple breaks down the front of the trouser and there should only be one small on at the bottom of the front where the trouser touches the shoe
the trouser legs are too long
The shoe laces should be re-done so they are horizontal instead of criss-cross.
Fix those things and it should look a whole lot better.
Thats what I think. It is my opinion.
