So, if the choice is the green one..
The engine pods have a nice overall shape, but it's a bit bulky and pointy at spots, so if I were you, I would try smoothening it up with slopes and plates. In addition, since the rear sides of the engines look pretty plain, adding some (or a lot) tech-like greebling there could look good. Something to make them look more engines and less just pods.
The cockpit pod (what was the term for it?) is neat and sleek, but looking like it's missing something. One or two antennas, perhaps? The cables, on the other hand, would in my opinion look better if unicoloured. Hence, would you happen to have pieces to make them all black or all dark grey?
The energy bindings look also pretty nice, but the trans-green colour seems lost in the green colour scheme. Therefore, would it be possible for you to make the binding trans-red or - even better - trans-orange? Those colours would stand out from the rest of the model quite brilliantly, I reckon. You could use the colour of the binding in adding some highlight lights, too.
As for the name, how would "Virulent Venom" sound? The lime-black colour instantly made me think of the word venom, and virulent sounds pretty good paired with that, having also a connection in meaning.
There, my 0,02 €. I Hope that helps even the slightest.
