You're on the very steep part of the learning process buddy. Feedbacks won't help you much, you just need to experiment and watch some tutorials first before making real ships (that you'd want to see in the game). I've been exactly where you are right now more than half a year ago, this is how I started: https://p3d.in/UYS8x . So my advice I can give you is, don't ever give up, because modelling is extremely satisfying and fun once you've learned some advanced tricks. So keep modelling and experimenting and don't be shy to ask me or anyone else in the community if you need help.
In my opinion though, I like the shape. Tip: don't rush with the details, just put the image you have in your head in the model first, then start detailing. You may get new ideas when you're on to texturing aswell.
