Well then this ought to go a looooong way:
Your suit is inaccurate in composition because you're not using a titanium alloy, you're waaaay behind schedule (but also under budget, that's a good thing), the crystalline gel layer in your undersuit isn't constructed, the crystalline properties of that gel aren't finished yet, indeed THE ENTIRE UNDERSUIT is not completed yet, the life support in your suit hasn't been implemented, air rebreather, waste management, and power systems need to be wired, AI interface needs to be invented and installed, and the human factor inside needs to be physically and mentally trained, and certified in high stress management so they don't flinch when injured and rip their limbs off, and they need the AI interface implanted in their brains.
The shield system is going to need to be invented, modified, reinvented, and installed, the structural integrity of the suit in entirety is going to need to be tested, stress tested, and painted, the helmet, Helmet Mounted Display, communications modules, AI interface, AI itself, lights, infrared and ultraviolet imaging sensors and 5x magnification system all need to be invented, improved and installed, and the gloves need to be threat level IIIA while also allowing dexterity to manipulate firearms and vehicle controls.
Other than that, it looks great!
