Looking better.
Also, about the Moloch's spikes:
Shivan spikes are always very long and thin. Look at the basilisk and mara (and also the astaroth, sort of) as well to see what I'm talking about. They jut out a lot, and are almost never short and stubby.
Looking at the retail nephilim, we see that none of these spikes are suggested except for the two on the missile pod. That's why I don't think it's a good idea to throw on random spikes here and there. If they're just placeholders for missile heads, that's fine. However, missile tubes might look a bit better. Seraphims, nahemas, and the other shivan bombers distinctly lack exposed missile tips.
Oh, and one thing I've noticed about the "cockpit' of this bomber. The walls around the triangular bit are paper thin. Definitely fix that. Perhaps use the lucifer's/cain's/lilith's/demon's head as inspiration for how to make the inside of that triangular bit?
