Hi. It's good to see that you guys are finishing this model. Though I imagined a new HTL Apollo in completely different style (there some parts which are annoying me, like the round engine intakes, but it's nothing important now. I just don't want to complain, because I already have an idea how to use this model
I like the idea of filling the space inside the engine pods, but:
I dislike the location of the thruster nozzle inside the pod. These ribs under are pretty but keep it in mind that they will be covered with thruster's flame during the game. And in my opinion it's moved too far to the upper part of the engine pod. And here I have two ideas:
Now it's "upper part" heavy. Apollo has a symmetric ass, that's why I prefer the idea of increasing the number of the nozzles to keep it detailed, but still bricky as the original.
But I think that you can make such thrusters as are now in the violet covered area. At the bottom pods we have a missile bank so logic says that is not 100% related for engine parts.
I hope that it will help
