I like how you did the back of the dress correctly and so far the sash is coming together nicely. The spacing of everything seems correct. I'd like to see the loin cloth longer, but that is more a preference of mine than a requirement
I do have a concern about the visible stitching of the tacking down of the leggings. I'd say it needs to be tighter, but then there is always the problem of needing it to stretch. Perhaps you could do it with back-stitching. With mine, I had a ridge made with a round shoelace. then the tacking was done just below the ridge so it could be a little loser without showing
Also, the grey straps on the boots and arms are a bit too light in color. A medium grey would be closer to reference. Perhaps, you could wash them with some darker colors so they don't stick out quite so much.
One other thing. The arm wraps should come down over the end of the dress fabric on the hands. That is just a detail to remember when you are getting ready. And if you are able to figure out a way to keep the middle arm straps from falling down, I'd like to know your solution. Mine does that all the time. Annoying really
I hope that you are able to finish it up a have it come together nicely
