In need of some advice

[Machine Gun Kelly]

Here are some of my SM. My problem just now is the Terminator. I am not pleased with it and I do not feel it fits in with the rest of the force.

So how about if I take the red and let it keep going all the way up to and including the torso, and on the sgt also let it cover the helmet.
On the ordinary Termie the helmet are metalic?

with ther terminator, id keep the legs as is, maybe make the TORSO red with a GOLD emblem or neckpiece, and turn the green to red. then you can touch up the rest as you see fit. (all green weapon if you want green on all of them)

your mixing of red and green (especially the shades) makes me think of christmas.

good job on the heads on the two that don't have helmets =]

I think the helmet is really throwing him off.. if you paint the helmet red with maybe some orange highlights you might be able to bring him back. Maybe paint the chest wings of the winged skull gold like said above, and keep the skull an actual bone color, it will give him that character youre looking for. The green helmet is just a bit too much green, but the shoulder pauldron will look fine. maybe paint the reinforcing members on the legs red and leave the legs whatever color you are working with, or visa versa. Hopefully this helps you out a bit.

I think the problem is actually that there's too much red on the model. As it is with the legs, shield and powerfist in red it creates a very pronounced divide running diagonally across the model. To tie him in with the rest of the models I'd have the powerfist in green, the greaves in metal and the same with the helm. As for the chesty eagle it's a tough call as you have a very dark green and a very light metal. I don't usually advise mixing metals but a darkish bronze may work well. I'd save the red as an accent colour like you've done in the tactical, captain and assault marine.
