I'm starting to look at forming my chest plate for my Late Crusader build, but I'm a bit hesitant on forming my PVC. I have watched tutorials and visited the Halls of Knowledge, but nothing quite answers what I'm looking for.
I really want to build the
Mandalorian Hunter Armor Set from SWTOR and I'm noticing that the chest plate has quite a bit of sharp angles, but appears to be one solid piece. Let me preface by saying I'm avoiding the hose in this design here; this art just happens to be the highest resolution image of the armor type which has a non-hose variant.
I haven't done much work with PVC, so it's a daunting task for sure. I'm currently just focusing on this red-outlined area, as the abdomen plate seems to be the easier part, and also slides underneath the chest plate so it will be a separate build.

When going about this, I have a few questions:
1) My initial thought was to divide it into sections; I would start with the bigger pieces, such as this and slowly build the rest of it off here. It's the flattest and most whole segment of the entire chest so it seemed it would be the "core" structure. Does this seem like a good starting point?

2) With that above, the rest of the chest plate is small segments at very slight angles from either that core piece, or off other small segments. Should I be cutting slightly into a sheet, and then folding it? Or should I cut out each of those segments, and at the connection point cut the angle I need into the edge that will be adhering to whatever the closest segment is?
3) I know I can just bend PVC to make the changes in planes that I'm looking for, but to me that seems like it will be more of a curved edge and not a sharp edge like what this armor has. Is this wrong? Does it depend on what I would be using to bend it?
