From what I can tell...the boot covers are pretty seamless, the pleats for the skirt are very crisp; nice job on that. The blue trim for the top is pretty good, too. I like the wrist cuffs as well, the 'triangle' shaped trim says attention to detail.
However along with a clearer photo, because if this is Satsuki, I can't really see the epaulets. If I'm not mistaken, she has the blue trim on her boots, too doesn't she? Unless this is a different version of her I haven't seen (I started getting into KLK myself.)
If not not then this is a pretty nicely crafted costume!
