This suite looks more like a nanosuite than an Iron Man suite.
At a first sight it's not as complicated as the MK42/43. But I might be wrong.
The unfold of each part could be made in a single piece where possible (or a couple of) and then all the lines and details could be traced with a wood burner or a pencil or carved with a blade. If I remember correctly there's someone here who did the same with a MK42 leg piece. And it came out great!
This would make the pieces sturdier, less time consuming to build because there would be less paper to cut. And hey, cheaper, because a lot less glue would be needed. And there would be less issues with seam lines.
