Thank you for your corrections, but I'm not a novic here/ and of course know the rules and use different sources for my drawings.
1. the underwater hull is quit wrong, the keel on the ship dosn't lift up like that toward the stern and bow, she has a flat bottom, and a flat keel the entire way.
I have used several photos of both ships in docks. I have no blueprint or another side drawing
2. the entire shape of the superstructure is wrong.
It's not so wrong , even in your picrures it is similar to nine
7. Many windows are wrong, placement of them are also wrong
I used sideview photos of AIDA
It's important to make sure the ship you post is correct toward the real things. We are infact drawing the ship how it looks in real life. That means using 100's of pictures and original blueprint as reference. not just one bad drawing, some are made for illustration in the media!
I used millions of photos of both ships
