looking great there bud,
firstly, your boot don't appear to be high enough. the officer boots from sovietboots.com are a great knee high option and have a great heel in them as well.
there is also the absence of the 3 belts and buckles around the boots and the armour cap on the toe
the undershirt should be something of compression wear as it needs to be form-fitting to prevent blousing.
as for the hands, i still paint mine and apply nails every troop but look into welovecolors.com for some form-fitting gloves to make it easier. you can also apply nails to them with hot glue to make it easier.
the zipper on the vest should not be visible so a flap of leather secured with velcro is a good option.
the belt buckle and greeblies should be enclosed on the top and bottom so they don't have a 'hollow' look.
i cant really tell with these photos and there is arguments on the topic but for your approval pics, you'll need a dark brown (yeah, almost black) face paint. the baldcap should be seamless so liquid latex is a good way to blend it to your skin via stippling and layering it up
make sure the bicep armour sits up higher also as it should be at the bottom of the shoulder armour. (more around the bicep than the top of the elbow)
as with all costumes, it comes down to your GML's approval.
i hope this helps with your build. its looking fantastic
