Cosplay Spartan Mjolnir Mark VII

[SpartanEC40]

Hello! I am new to cosplay, I've been doing it for a year now and I've created a cosplay of Ghost from Call of Duty and an ODST. Now, I am going to make a Spartan Mark VII for a contest in November. If you have any tips for cosplay and/or for performing, I'd love to hear them. Here’s what I’ve done so far.

hello! it's been a long time since I last posted but here is what I've done for now.
But now I am stuck because the 3D files in EVA foam are too big for me and I don't have armosmith and not enough money to pay for it, so I turned to 3D printing, but the files I am using for free are not complete, so I am stuck. If someone could help me, that would be really nice because the convention for the cosplay I have to do is in 1 month and 15 days.
