I'm not a big fan of the baby blue GW is using lately, I prefer the pre-heresy color scheme. I haven't decided yet which company and pack marks I'm going to use so they are not totally finished. I've changed the side of the yellow shoulderpad so both the power armor and the terminator armor got it on the same side.
As for the bits I have combined vanilla SM and Space wolves and I think they look wolfy enough. I will only go full SW bits with the Wolf Guard to make a difference.
Right now I'm working on 3 more terminators and aiming to finish them next week, so expect new posts about them soon!
