Hi, interesting start... But as the others said there are some errors
- crediting
- the picture is a .jpg and rescaled, better you uppload it as a .PNG file
- swap the rear gun with the aa-weapons so you have more space for the underhull part
- you have to place the missiles you use above the ship, just look at a clean template and you know what I mean
-put the 127mm (?) gun in the front behind your main gun
That's it for the moment, hope it will help you
