I really like your new model. It really proves that you have a lot of skill in building ships mate. The custom "armor shell" is cool and new, yet looking bretonina. I really like the "helmet" frontal part. You can put windows in its holes. Also what Thunderer said +1. These multiple "engines" on its back should be turned in to hangars (then it will look similar in design to the original Prototype in Southampton which featured such hangars and that was the main intention). Just make them more "Hangar" orientated. Put something on these side engines, they are exposed. The ship looks nice from the sides but once u rotate to see it from above it does look small. You need to make this "hull/shell" bigger (size increased x-0.5 maybe) and definitely put something below the "shell" with windows (as super structure) to make it look bigger. The backward part is nice, clean and very detailed - following the Bretonian design and yet it's fresh.
Overall - it looks really good as a basis model to start improving. Currently (considering the bridge and its windows) it looks like a slightly bigger Destroyer. So just like the old model I will recommend you to put something between the end of the "armor shell" and the beginning of the backward body part. Something to make it longer and bulkier. Won't give images like I did before because I want to see your own model imagination considering our feedback but with no direct guidance.
Keep up.
