The only thing I'd suggest is that depending on how the armor actually fits, you might consider trimming the ab plate a little from the bottom. Since it is taller, it looks like it is going to sit very lower on your abdomen which means you won't have a lot of forward flexibility.
One more thing, I can't exactly tell but in the pic it appears that there are splotches of paint on your armor. I am guessing it may have come from a clogged spray nozel? If you're going to use it as weathering, cool. If not, you might want to wet sand those areas smooth and add another coat or two to even it out while remembering to spray a scrap piece of cardboard or something with a swipe or two of the rattle can and then move directly to your armor. It'll spit all the blobs of paint in those first two passes and leave a better finish on the armor. Do that each time you start/stop a spraying pass.
Otherwise, looks like you're good to go!
