Let me think about it some more. Perhaps I am tired.
Edit: I realised why.
The wings are short and stubby, intentional no doubt, but can you just for the fun of it lengthen them to see what it looks like? (Like four times larger.)
Also, make the wings eventually flatten out to be horizontal.
The rings on the top. I know the Luxury Liner and the Osiris have them, but, no. Remove them?
The aerial on the bottom facing forward. Why is it there? (Looks good, just curious.)
The projecting thing in front of the rings needs to go in my opinion. (Or, can you zoom it in, because to be frank I cannot see it too well.)
