Thanks.
The detail isn't ruined in the sense that the model is a miscast, but the placement of certain vents in the mould has led to bits of resin in awkward places. This is a flaw in the mould itself (from what I'm reading, they've had to add a lot of these vents to many of the moulds to reduce the problems with surface bubbles), so not something that would be fixed by swapping out, unfortunately.
If you look at the image here, you can see the cable running along his arm to the Force Sword. In the area on the underside of his wrist, there were two separate chunks that needed to be cut away, however even with the smallest blade I have, I can't fit it in between the arm and the body in order to be able to cut the remains away in an accurate manner and attempt to re-cut the ribbing in the exterior of the cable, so the best I can do is scrape at it with a piece of emery cloth until it's smooth, paint it dark and hope that nobody notices.
