The smile says it all!
Congratulations on your new kilt. The first of many I'm sure!

Personally I like to wear my kilts about 3/4 to 1 inch higher so they come closer to the top of the kneecap. Usually not below the middle of the kneecap.

A good wide sturdy belt really feels good around the waist, too.
Agree on the shirt tucked in.
You're going to look great!!
