I'd love to see pictures of the whole thing too. As Wolf said, it reads pretty good.
The kinds of historical accuracy errors you probably have are the same ones that plague all of us, just because commodity off-the-shelf armor usually is made with certain flaws. It typically lacks the tailoring that's necessary to make it act like a "second skin". This is particularly true with the sleeves and leggings. Looking at your avatar photo, it looks like the sleeves are about 3/4 or 2/3 length, and of course you have the MRL style mail gauntlets. In the late 12th and early 13th, this should be a full length sleeve with integrated gauntlet, and the sleeves should be tapered to contour with the lower arm instead of gaping open. Since what you have is riveted, this would be hard to change on the existing hauberk, but not impossible. The half sleeves work well if you move into the early 14th and start wearing some plate elements. But personally, this is one area I don't mind cheating on, just because of the availability of armor and the impracticality of tailoring it yourself.
This goes for the leggings too. It's hard to make a "one size fits all" offering that will fit people and move correctly. Most people end up with a baggy mail tube hanging over their legs. Unless you make it yourself, I'm not sure this can be avoided. But since you mentioned it's butted links, you can always taper it by removing material, and add some expansion triangles around the knee area so it still bends properly. The legs are probably the hardest to deal with, because there are so few offerings out there, and as I'm discovering, the tailoring of it is just a nightmare. Most people, I think, tend to overlook this and don't wear leg armor if they're trying to do a 12 century sort of look. The fact that you have mail chauses is awesome.
Please don't take any of this as criticism! It's great that you're including all of these components, and I'm just pointing out these things because you asked. My kit has suffered from some of the same problems, and it's an on-going struggle to improve it. In some ways, I'm still less period correct with round butted aluminum mail, but I started making it before you could buy all this great riveted stuff that's out there now.
It's always useful to know where you are inaccurate and where you can improve things.
Speaking of the mail gauntlets, how do you like them? I just ordered a pair myself, and my plan is to take the plate cuffs off.
