I have no idea what you are going on about with your comment on gun sizes. The drawings I have posted are 117mm/4.5" guns, which I use for my AU in place of the 120mm/4.7" a lot earlier.
That was meant as approval. 120mm is the perfect caliber for a destroyer in that era. I thought my statement made sense in itself - my fault. Next time I try to make the wording so precise that not even someone who wants to feel offended can construe it as offensive.
The forecastle issue remains. I'm not comparing your destroyer to Antelope, which is 350 tons smaller. With the units closer to its size, it compares badly. The whole forecastle deck of your destroyer is 34 meters long; Javelin's is 40,5 meters long, Onslow's 43 meters. A Tribal has nearly 47 meters. The issue is less pronounced for the free deck space between the forward gun and the bow, but yours still has the shortest at 15 meters, against 16,5 meters for Onslow, 17 meters for Javelin, and 18 meters for a Tribal. I'm afraid your destroyer will be the wettest of them - and as, like you said, all are wet forward, this makes yours very wet indeed.
You don't have to defend your choices, you don't have to heed my advice (I certainly don't heed yours) - in AU, anything goes and that's OK. But please consider I usually don't comment on other people's kitbashes unless I see some real potential there.
That's what I mean:
