First of all, welcome to the Shipbucket!
I'm afraid I'm not having a good news for You. Unfortunately, this ship still needs significant amount of work to do, and there is also some to do about SB standards.
First of all, it should be directed in other way (shouldn't sail to the left, but to the right).
Secondly, it should be on standarized template, which can be found here:

And credited with bigger fonts (and in Arial)
Also, the black contour lines should be more clean (now they look like hand-drawn), and there should be black contour on windows/portholes.
The gun should be - if possible taken from parts sheet. Some of them are here:

and here (but these are often outdated):

I'm also unsure if the ship on drawing has proper size (if You scaled it properly) - 1 pixel should be 1/2 feet or 15,24cm, but I admit I didn't check it with the brochure You've linked.
I'm sure You'll get lots of good advice - and if You'll listen to it, I'm sure You'll be able to make good drawings.
Good luck!
