We're all here to learn man. The only reason I say the things I say is because I spot something that can be done better. Constructive criticism is just a part of it; it helped me create better models. In the end, it's your model. You can ignore my advise, or do something with it. For example, the way that indent on the secondary hull visually flows into the base of the pylon? That's *awesome*! It is visually pleasing; no need for that bulbous thingy aft of it IMHO.
In the case of the Repulse, that advise had to do with your modeling methods. Heeding it would mean that, even if you won't change the Repulse, you will be aware of the number of segments you're using in the next model, meaning a smoother and cleaner model. Your render of that model showed the low number of polygons quite well, and because I thought that a shame I commented on that. Because I really want for your models to look the best they can!
