Hello!
Like @Lt. Dan said, pics are hard to tell some details. From what I can speak on, it's good for a first suit up.
1. The belt pouches need adjustment; that's an easy fix of just sliding them to correct position. They shouldn't move THAT much while walking. I would agree with Dan on the box placement. They shouldn't be behind your kidneys.
2. The biceps should have "...two black elastic cord straps." It's dark, so they may be there, but I couldn't see any evidence of them.
3. Strapping shouldn't show in your midsection. (This actually led me to my next discovery)
4. I think your midsection (ab, kidney, butt, cod, belt) is sitting too low, causing your thighs to be low and the sniper knee to land weird on the shin (This is where Lt. Dan's comment comes in). I would recommend finding a way to secure your midsection higher so that the rest falls into place better.
5. (Being picky on this one) I would check the color of 'metallic grey' on the accents (chest and ab). It seems a little bright in my opinion. Tamiya TS-40 is ideal.
