I have taken the liberty to do a quick hack job of your drawing to illustrate what we mean by 'balance'.
The parts you are using and the hull can work together you just need to put the parts in the right places. You are learning from each drawing you do so keep trying. Remember that if you can get one of your Alternate Universe designs to look like a real ship just 'different' then you will have succeeded.
One of the best bits of advice I have got in Shipbucket is: Your design should look like all the parts go together, not just cut and paste.
You have the right ideas just need bit better execution.
