Nice bullet impact! That armor sure is tough.. it could use maybe a touch of shading, though. Hm, I think you're getting lower ratings because too much of it's out of focus, so it's hard to tell how it looks, and then there's a big, and distracting, mold line on the backpack. Removing a few key, large, easily-viewed mold lines is the first step to better minis. You should really remove them all. Keep it up, and happy painting
