Looks pretty good to me. Nice build. Only comments I will make are on the colors. Looks like you used Forest Green and Military Brown as in Nato 3-color camo. The Koreans don't use those colors. The color scheme is basically the old US MERDC colors. Better match is OD Green and Dark Tan for base colors with Sand and Black for the smaller squiggles. Here is a photo of one from Korea.

I did a pair of K200 KIFV and K163 20mm Vulcan ADA Gun too. Here are mine:
And the whole ROK Checkpoint Dio they are on (based off an actual Checkpoint in Korea)
For an extra bonus, Trumpeter's K1A1 to go with them.

I also have the Academy M48A5 in ROK colors as well, no pics though.
I was stationed in Korea for as year, saw lots of interesting ROK vehicles with this interesting color scheme. Academy also does some great ROK armored troos to go with them as well.
