Nice to see this ship done (hopefully we'll see it also in earlier years? any chance for it's Malaysian half-sisters?
)
But I'd say that I'm not sure about shape of certain elements (base of funnel? shape of hangar, which, on Your drawing seen from above would look like a simple box, while in reality it was more like T shaped). Also, I'd say You could add more small details (all that equipment that can be seen on the photographs hanging on the walls of superstructure
), not mentioning all moorings etc. etc.
Hope it would help (sorry for drawings not being quite horizontally-oriented
).
