@ Mao, due to GMT and my little free time I am unable to work with someone else at this stage. As for unlucky_soul's model I already pointed in his thread that his ship looks good for an improved Destroyer with forward gun. I do not like the scaled up dessi+rotated dunkirk variant. (thats my opinion ofc)
@Thunder, you've raised some good points and I will consider them. "No time no resources" RP reason for the ships to look similar is justified by the lore and I see you understood that.
I've done some comparisons between the current model and this one and this one looks a way shorter and because of that I will further work on it by improving the main body, making it longer and tweaking the head to make it not look like scuttled dunkirk (not too much ofc). Once my MK2 idea is ready will upload it for further commets. Thanks for the feedback so far.
