The design of the aerial craft does look pretty cool and you have used the objects very efficiently to get the current look.
However, I see you used only 30 objects in this mod. This means you used less than a fourth of the 128 objects at your disposal.
You could have done lots with those 98 objects. For example you could have added some smaller details to the aircraft to really push the look of it to something really epic or add some kind of landscape below to make some nice scenery or better yet, add something to the red fighting area itself to make the gameplay more interesting. To be honest with that many objects you could do all three.
When your mod is at the state your mod currently is, you should still be asking yourself: "What else could I add?" before releasing it.
Try to get the full potential out of your mod instead of rushing it out the moment it has the minor resemblance of something finished.
I hope to see you demand a lot more from yourself in the future, as it's not really that difficult to create really stand out mods and I'm sure anyone willing to put the time and effort in can achieve it, even with their very first mod.
