Here's what I see (Not trying to be mean, just some tips on where to go next. ):
1. You need to smoothen the edges of the biceps and forarms. They point out and aren't smooth at all.
If you leave them like that, you'll get some really hurtful armour kisses, and to be honest, it doesn't look good.
2. Have the ab-plate and bqackplate adjusted so it gets snug fit to your body. Make sure it comes up beneath you chest plate.
3. Is your thighs fastened by velcro in front? If that's the case, I suggest glueing the thighs together front and back.. They should be large enough so you can slide your foot in. Use Stukatroopers build as a refrence on how to do that.
4. You habe the right thigh on you left leg and opposite.
5. You need to get hold of an ammo strip for the right leg.
6. The kneeplate shin seems to be on the wrong leg. It should be on the left. Just switch the two shins.
7. You will need some hand plates.
You have correctly coloured ab buttons, which is very good, and the helmet looks very good as well.
You seems to have some work in front of you, but that's the fun in the TK-business.
Good luck.
